Hi Glen,

Well, what I think is nice about JADE is that they have done a LOT of  
the inter-agent management for you, and it's actually pretty easy to  
set up and get going. It's been around now for over 4 years (maybe  
even longer), it's open source, and the developers have recently come  
out with a book (http://www.amazon.com/Developing-Multi-Agent-Systems- 
Wiley-Technology/dp/0470057475/ref=pd_bbs_sr_1? 
ie=UTF8&s=books&qid=1197055589&sr=8-1), although I think the  
documentation is decent enough.

Good luck!
steve
