Most avahi features can be disabled.. if you simply want this you want  
a very cut down avahi-daemon (should only need libdaemon) and libnss- 
mdns.. if you try to compile it will tell you what --disable options  
you need on the fly, or you can check ./configure --help

Heres a good start:

--disable-glib --disable-gobject --disable-qt3 --disable-qt4 --disable- 
gtk --disable-dbus --disable-expat --disable-gdbm --disable-python -- 
disable-pygtk --disable-python-dbus --disable-mono --disable-monodoc

You may or may not want to --disable-autoipd if you are interested in  
the automatic IP feature or not.

Then you can just run avahi-daemon and it will publish the local  
hostname and use libnss-mdns for resolving them.

Let me know if you have any specific problems.

Trent
