That's ok, I appreciate all the trouble you're going to already! I
couldn't possibly ask you more :-)

Ok. I've been doing some reading, and the little I could understand, I
think the solution would be to mark all packets to/from that
particular machine with iptables MARK or somesuch, and then have a
class in tc set to whatever bandwidth I want to allocate, and some
other tc command to bound those marked packets to that class.

This is all theory, of couse, I haven't the slightest idea how to
accomplish this, or even if this isn't complete hogwash :-)
