Hah, well since it comes from avahi.org, one can assume that they know 
what they're doing.

One thing you can try is to reverse the roles and move the publisher to 
the receiver and vice versa. (a broken multicast network is a 
possibility but it might not affect both machines)
You could also try to strace the publisher to make sure that it wakes up 
when being queried.
Once you get timeouts, does this affect all the services on that machine 
or just your own one?

Hope this helps
Antoine
