Yep, makes sense to me. Not sure if you can leverage the open source codebase, but even still I doubt we're talking about real licensing issues here or just limitations of the toolset.

Is it patented? Probably. Doesn't seem to have stopped anyone from using it from what I can see thus far. And I surely doubt anyone's interested in the scale of devices we're talking about anyway :)
