Yikes. I completely missed the changed direction for Stackless and think I posted not too long ago that it wouldn't be admitted into Python because of compatability problems with JPython. That's obviously wrong (see the slides) and there's more info at http://www.onlamp.com/pub/a/python/2002/02/14/pythonnews.html
Apologies if this was posted here before (it's old news - from Feb this year) and I missed it.
