At the core of REST (representational state transfer) is the concept of resources which are assigned a global identifier (a URI) allowing said resources to be utilized through standard interfaces. The poor man's (non-geek) explanation is that REST lets you interact with almost anything through HTTP.
It's pretty interesting to see the smaller, bleeding edge vendors figure this stuff out before the BigCo's. This should put some pressure on those who still seem to be missing the Cloud blimp.
