my "dummynet" stuff can be used as a generic bw limiter for TCP (note -- TCP
only, not all IP traffic). It is pretty much straightforward to make it
work on specific IP addresses. It requires a little bit of more work to
move it down the protocol stack to apply to all IP traffic, or to all
traffic through a specific interface.

If you want to try it, it's available from my page

	http://www.iet.unipi.it/~luigi/research.html

I have been using it on my personal workstation (2.1R) for 4 months
now, so I'd say it is pretty stable!

	Cheers
