"Patches welcome!" (as are questions/suggestions/complaints/sarcastic 
taunts/etc) :-)

If you look in the mailing list archives, you'll find a couple of 
messages from people porting netcf to other Linux distributions 
(although none has gotten to the point of a patch submitted for 
pushing). It would be really great to see netcf running on other 
platforms, as all the iface-* functionality in libvirt (and thus 
virt-manager) would magically start working on that platform).
