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@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,
