I'm a big fan of R and of rlm in particular. I have to agree with your
comments about Rpy, though I think their plans for it head in the right
direction and give hope of a better interface.
But, yes, I would support adding those capabilities to SciPy. I have Rpy
accessing rlm in a little product right now, and it would certainly
simply life!
