I think you can.  I was about to test it for that earlier this evening
since I'm on @Home, but a quick telnet over to an outside system a
friend of mine loaned me for testing shows that my port 80 isn't being
blocked (yet).
I would think in dhs.org's case, you just put the :8080 (or whatever)
after your IP address.  For auto-update scripts, you could probably hack
them to attach that to the updates they submit.
