It should handle it; but I'd still want someone to check out various edge 
conditions and pathological cases.

The presence or absence of a DHCP server is not a good indicator of the need or 
desire for LLA and/or mDNS. It is quite possible that the system is in a mixed 
environment where there are some systems which are LLA/mDNS only, others which 
are DHCP/static/unicast DNS only, and others which handle both.

I believe that there is a way to announce routing service via mDNS-SD; but I 
don't know the details. (I would be astonished to discover that the people who 
developed the zeroconfig design left that bit out...)
