IBM cranks up client software push
November 9, 2004
Big Blue on Monday announced software products designed to reduce PC software costs by running the same applications on Windows, Mac OS X and Linux. The project grew out of the company's attempt to lower software costs through the use of Linux, said Scott Handy, vice president of Linux and open source at IBM.
The software, called the Open Client Offering, combines IBM's Lotus Notes and Sametime software for e-mail, calendar and messaging; WebSphere software for server-based applications; a special version of the open-source OpenOffice.org software suite; and Lotus Expeditor for hybrid applications that can run either when a computer is connected to the network or not.
The work sidesteps some of the thorniest issues of the long-promised but as-yet unfulfilled vision of using the Linux operating system on desktop computers. The open-source operating system is widely used on servers, but it's still a rarity on personal computers where Microsoft's Windows dominates--in part, because of the difficulty of moving a multitude of Windows programs to Linux.
To get around the issue, the Open Client Offering uses software that grew out of the IBM-launched Eclipse project called the Rich Client Platform (RCP). This package includes a "runtime" foundation that lets the same software run on multiple operating systems, presenting the application with a native look.
"One code base runs on Linux, Windows and the Mac," Handy said. "With the Eclipse RCP runtime, a Windows application is rendered with Win32 (the Windows interface). Linux is rendered in GNOME (one Linux interface). The Mac version looks like a Mac native application."
The technology is conceptually similar to Sun Microsystems' Java, which was launched under the "write once, run anywhere" tagline and which also incorporates a runtime component.
IBM rewrote the OpenOffice.org suite--a Microsoft Office competitor that includes a word processor, spreadsheet and presentation package--as an Eclipse RCP plug-in, Handy said.
The software grew out of IBM's attempt in 2004 to move many of its own PCs to Linux, he said. With the Linux move, IBM had hoped to reduce total cost of ownership (TCO)--the cumulative costs of purchasing, supporting and running computing equipment--but instead found that costs rose because the company had to support two separate software suites for Windows and Linux.
"We determined that the TCO savings probably wouldn't materialize if you had to support both environments," Handy said. "We did a hard re-look at the whole thing."
Linux is still widely used on desktop computers within IBM, Handy said. Among those using it are employees at the Linux Technology Center, IBM operations in Brazil and India, Linux sales groups, and the China software development lab, he said. "We have big pockets of Linux users," Handy said.
IBM rewrote the Linux version of Lotus Notes 7 to use the RCP technology, and Windows will get it with version 8, due midyear, Handy said. The Mac OS X ability is scheduled to arrive by the end of the year, he added.

Is OS/2 alive still? I keep thinking I should add it to my OS collection but there doesn't seem to be much activity if there is a FOSS community around it paying for it can't be justified these days.
Either way, common administration tools for the three major OS is a huge step. If someone can develop a FOSS replacement for Exchange Server, that'd be another huge step along side this one.
IBM is developing a desktop software system to address managing multiple OS within a network.
I read that as IBM developing "desktop software" as a "system" as a single tool to manage a mixed OS network and user base.
So is OS/2 coming back for another round? Not yet but it's not a dead as it looked to be a year ago.
For competition, Windows right now is still looking at Linux. Linux came in and took a lot of the market that MS thought they had locked up and has the potential to grow further as more software like this from IBM, the .NET initiative by MS (Mono) and their grandfather Java make the differences between the OSes less relevant.
Patience is recommended though, any action is going to take years to accomplish now since established systems will be replaced now instead of new systems being added.

Linux is rendered in GNOME (one Linux interface). The Mac version looks like a Mac native application." The bets are off as to whether the "chained/caged up" 800lb GORILLA which is OS/2 can kill three birds (Linux, Windows and the Mac) with one stone!

- OS/2? y'mean eComStation
- by ben::zen February 12, 2007 7:17 PM PST
- In any event, eComStation, as you are so fond in pointing out, is based off OS/2, and only has support for Win 3.x apps (it says so on the main page), or Java, and this isn't Java. So no, OS/2 won't run this. "Chained?" Where does that come from? And anyways, it's been replaced. Don't you have a warp drive to die fixing, Commander_Spock? Somewhere relatively near when Kirk yells, "KHAN!!!!!!" and the Genesis device blows up?
