The main thing I was waiting for was confirmation that the range coder
didn't violate any patents, as far as everyone was concerned.

I have this confirmation now, actually.
I got embroiled in working on gcc's 3.1 release, so my subversion work
got shoved to the back burner.
Then I moved from Boston to Maryland for the summer.
You know, life getting in the way of subversion hacking.
It's worse though, since I lost the hard disk i was keeping subversion on
during the move.
Summer law clerking is also keeping me very busy.
So it might be easier for someone else to pick it up and run with it if
they want it done in the next month or two.
But I still exist, and am around for questions.
And I *will* get to it eventually, just not anytime soon.
