On Asterisk 1.6.2, your only option for distributing device state is with 
res_ais. I've used it in a labbing system and it works well -- the caveat is 
that your machines need to be on a low latency network (i.e. LAN).

With Asterisk 1.8 (currently 1.8.0-beta1) you can use XMPP to distribute your 
device states over the WAN. I've made it work with the Tigase XMPP server. More 
information about it can be found in the doc/distributed_devstate-XMPP.txt file.
