I also thought that the packeteer-like approach was very clever,
so once i sat down trying to implement it in dummynet.

Then i realised (fortunately before writing any additional code)
that since acks are generated in response to incoming data, you
achieve exactly the same result by pacing incoming data (before the
stack has a chance to see them, as dummynet does) or outgoing acks.

This also saved patent-related hassles :)
