It's a while ago -- I went through this in some $BIGCORP.
Windows ops insisted in having the internal top level as
.local (don't ask :-)

For me it was as easy as kicking out Avahi. For the Mac
users it was... interesting :-)

Whatever. Your net, your rules. Just make sure the software
you use plays along (Avahi is fond of .local because of
mDNS, for example).
