name all the uses for samba

[Dragoncrest]

	Ok, I've gotta convince my boss to switch from windows 2000 to freebsd for 
all our internal needs.  So far I've half convinced him, but I've hit a 
snag.  I know that Samba can be used for a lot of things, and I'm trying to 
tell him all the things that Samba will do, but I can't think of many.  Can 
you guys name all the uses for samba?  I've already talked him into 
replacing our windows firewall, mail and other basic servers with freebsd, 
but we've still got a couple of domain servers to get rid of and I know 
that Samba can replace them as well.  Can you guys help me out here?  Maybe 
toss in a little TCO jargon so that he sees it both from a technical side 
as well as what matters most ot him.  Money.  THanks!!
