I figured that out now...  (Hmm  Wish I still had those TCP/IP books)

But that's the trick isnt it....
I know that's what I need to do, but how do you make a rule that just gets
these upload acks?  Or alternativly get a rule that matches everything but?

Ideally I'd like it to work with any TCP app, http, ftp, icq, dcc, smtp,
whatever....

And also, should I just make one pipe for all the non-upload-ack packets
(the ones that would fit in the 22kb range) or a pipe for all and two
queue's with different weights?

Which is the more elegant implementation.

Sorry for the moranic questions but dummynet is new to me...
