I have a project that requires me to simulate a link with varying but

I don't think dummynet can do this in its current form. Based on
actually dummynet never does reordering within a single pipe, even
if you change the delay on the fly.
But this said, you should explain "varying but well defined delay",
Hitting up Google reveals someone hacked Dummynet to introduce per-flow
randomness in a uniform distribution:

However, they included entire source files against FreeBSD 4.5;
forward-porting should hopefully not be too tedious for an interested party.
