I have no idea why it wasn't implemented before except maybe simply for lack of interest.

Two years ago, I remember there was some discussion about a modular TCP congestion control framework in FreeBSD to ease the introduction of new CC algorithms. It was among the big TCP overhaul going on then with some part committed in 8.0. There is a branch dedicated to this project but I have no idea if it's still active : http://svn.freebsd.org/viewvc/base/projects/tcp_cc_8.x/

You might want to contact Lawrence Stewart (lstewart at freebsd.org), Andre Oppermann (andre@) and/or Rui Paulo (rpaulo@). They might have patches that could help you or at least they can give you some pointers.

Good luck,
