ah yes I heard of netlimiter before, thanks for reminding me =)

Hmm. Maybe if I run the Internet Connection Sharing related services in their own process I could limit it with this app on server side.

Ultimately I'd have to set up software based traffic shapping on linux, which I plan to merge my connection sharing stuff to soon.

Anyway getting off topic, should there be a feature request to throttle a DCC, or is it technically infeasible?
I think a lot of people would want this, and many other programs supporting file transfer (eg ICQ) support this.
