The client CVS communicates to the server CVS via a
client/server protocol (which, I believe, is typically
sent over a rsh-like protocol).  Since the server CVS
is running on the server, it is able to execute things
on the server.

I think files are copied through the client/server
protocol.  I don't think diffs are sent (nor can they
be sent efficiently).  There has been some talk of
using the rsync protocol to do this, but AFAIK, it's
only been talk.

I'm not that familiar with the use of restricted
shells, but I've heard SSH can be setup to do what you
want.

Theoretically, yes, and I can't fathom why it wouldn't
work in practice, but I haven't tried it myself.
