(My apologies, if this is spamish), but just to verify what is going on:

git fetch git://host.local/...
results in a DNS lookup ?

Kyle, did you verify the lookup with wireshark or a similar tool?

Jonathan, (I'm good in searching, but bad in finding)
could you point out where the source code for the git package for
debian is ?

I recently learned about mDNS, and will probably do some tests
and experiments later, and would like to test the lookup feature
of "0010".

Thanks.
