[jdev] GSoC2011 project idea

Hi..
In our first approach I'm counting on ARM9 based embedded system with
linux running on top of it and probably Java as programming
environment (there will be also implemented ReST access to the
network). I designed HW platform which is agnostic to the particular
WSN and gateway would pose as abstraction, so it's exactly ass You
said. Later I would like to re-implement the idea (if turns to be
usable) to some more lightweight device. I was thinking of XMPP to
pose as tool for gateways to distribute events and to exchange
configuration among them.

The big problem is that you need a full network stack, and then enough processing power to crunch the XML. Is it possible that the XMPP gateway is a bit more powerful with access to say a ZigBee network on one side and the XMPP system on the other?
