Depending on your setup. If you're actually running a Windows domain
it can get interesting, but generally speaking Windows will
automatically set up a local browser per subnet (through a voting
process among the machines). My understanding (which may be
incomplete, or incorrect, or both) is that if you have WINS, and
everyone's configured to use WINS, you can happily work cross-subnet
shares, but they won't necessarily show up in the network
neighbourhood. Samba can happily reconcile some or all of these things
depending on configuration.

I dunno about Novell/IPX over tunnels, but I do know that if you've a
spare NT server knocking around you can set up a Novell Gateway on it
that makes it visible as a regular windows fileshare. A Linux box can
also do this using the ipx and ncpfs utils. It's an imperfect
solution, but it does work.

Appletalk is happy to go over TCP, and from talking to an Apple
employee I get the very strong impression that Appletalk over any
other mechanism has been deprecated since MacOS 8.5. netatalk is the
Linux tool that may help out in case of any difficulties here.

I think it's feasible; I also think, in my limited networking
knowledge, that setting a linux box or boxes up as a bridge over the
encrypted connection might be the easiest (not best) way to make all
these things "just work". You will have latency issues if the VPN is
running over a slow link, though. Especially with Windows.

I've been playing with FreeSwan for the last week or so, and it's
pretty easy to set up once you actually read the docs. Also, it's
chock full of debug information for figuring out what you got wrong. I
understand that some of my work colleagues have experience with CIPE,
so one of them may pipe up with more info on that. Personally, I don't
know the first thing about it.
