Realized that I replied to Brian directly without cc'ing the list. (I
shouldn't answer mails when it gets too late...) So here is the reply
for the list:

This is because altqd only operates on the outgoing queue of an interface,
so the uploads are not matched and get full speed. If computerA would have
been a router with two interfaces you could limit the bandwidth on the
interface that sends the packets out, but not with a single interface.

I read something about filtering on the ingoing queue on the altq mailing
list. If somebody has done that successfully with OpenBSD please drop me
a line so I could solve a similar problem here...
