The RTL-VRP code? I don't think it's under active development
(I haven't seen any posting from John in a while). You might
contact him directly to see where things stand.
I think we had some minor differences in how we thought it ought to
work, but nothing drastic. Of course there were also the compile-time
issues since I my recollection was that it was a traditional iterate
iterate iterate until you reach a fixed point solution.
