searching around on http://www.multicastdns.org/ it seems that Multicast
DNS packets use UDP port 5353. So this service needs to be installed
alongside to regular BIND. mDNSresponder should be fine, however i
haven't yet tried much with it.. So far i just found out that SRV RRs in
mDNS regarded quite special to regular DNS and thus will not affect any
regular DNS infrastructure from what i read. 
Point however is that it really sounds like every PC needs a local
multicast IP and thus will fail on *EVERY* regular (ipv4-only)
installation that does not insert some IP from the 239.255.0.0/16 range
to eth*. The only chance for hosts to automagically work in a LAN will
be IPv6 that does usually (if not disabled forcefully) set link-local
IPs by default.

If someone could shed some light how the GM setup for a host is meant to
be and what a SOHO setup should look like and how it could be verified
(apparently not with regular dnsutils), i'd be thankful for some
pointers.. I'd definitely add this to the official or inofficial FAQ
with some pointers how to debug problems.
