Why doesn't he find out about the first user? Is this a bug in Avahi
or intended behaviour? I still don't understand. :-(

Same question here, why isn't he notified about the second user?

Hrmm. The were some changes in SVN recently where the c# stuff wasn't
up-to-date with the client library in regards to method
signatures. 

Please update to avahi 0.5.1. 

(Current SVN is broken regarding avahi-sharp too)

This is very suspicious. The Resolver timeouts after 10s or so, if you
don't get that, the error is on a very high level.

Hmm, thanks. Honestly I cannot make much sense of the ethereal
snapshot. I cannot distuinguish which query was issued by which client
app. Is there any chance that you could repeat this stuff on two
seperate hosts with different IP addresses?

I personally don't know C#. snorp, could have a quick look on the
source code?
