I think I didn't state my question clearly :( I get that if you know the
endpoints, or one side, or the protocol or the ports involved QOS isn't
'hard'. What my question really was getting at was Simon brought up the
normal QOS stuckee 'BitTorrent' (substitute any other p2p sharing
application which most folks claim is 'all illegal content anyway'). I was
wondering how QOS was supposed to work on that traffic, given it's
port/protocol agililty.

I suppose if you had some special traffic you could qos up that and down
everything else but that wasn't quite what Simon was getting at I don't
