Last November and December, 19-year-old entrepreneur Eric Simons, low on money as he built his startup ClassConnect, started living surreptitiously in AOL's Palo Alto, Calif., building. For two months, he slept on couches that he discovered were off building security's rounds.

Eventually, he was discovered and kicked out. But before that happened, he was living on a dollar a day and enjoying a prime Palo Alto address. Even if he had to hide to do so.
