Yep, that's part of the purpose of dbus. What you want to do is watch 
for the client's unique bus name to lose its owner. The unique bus name 
will be in the "sender" field of any message you get from the client.

http://thaiopensource.org/development/suriyan/wiki/DbusNotes may be more 
helpful than the official tutorial if it isn't clear what I'm talking 
about with the bus name etc.

Surely someone on the list can point to a simple example of watching 
NameOwnerChanged on a unique bus name - anyone have that code around?
