Anoncvs will let you do this.
cvs -D $ANONCVSROOT co -r$REVISION -d $WHERE_I_WANT_IT $WHERE_IT_IS

You can use CVSweb for this quite ably. That's not a great
solution for generating patches, but it's decent enough for trolling
around the repo.

For that, you'd most easily check out the directory in which the
files in question live, copy your local version into it, and use cvs
diff. The repo information is cached in the CVS/ subdir, so it all
works nicely:
cvs diff -u myfile.c

CVSweb is your friend. http://cvsweb.freebsd.org

It's unnecessary. Use the -d option to cvs co to check out the
subdirectories into a convenient place.

If you can afford it, retire the box to mail/firewall duty. A
bare-bones 2.4GHz P4 system can be had for $500US if you shop hard.
