[ in reference to the UCB/LBL SACK implementation ]

I don't think so; someone else has been working on a seperate
implementation for NetBSD.

Once the initial implementations are out it will make some sense to
look at multiple ones and pick and choose, but it will probably be
easiest to adopt the one written for NetBSD.
