I found interesting examples in the "Programming Jabber" book. It has 
one neat application that ties presence to a light sensor on a Lego 
Mindstorm module. When the light goes up beyond a particular level, the 
lego unit sends a readout to an infrared receiver, which then passes it 
on to a laptop running Perl. The perl app running on the laptop (or 
desktop. Mine is a laptop that talks to the network via Wifi) sends the 
"presence" via a jabber client. Your buddy list shows the messages as 
presence, etc.

All examples are available athttp://examples.oreilly.com/jabber/
