Andrew, thanks for the reply.  I saw a message about your work, and have 
bookmarked your "Adventures" blog.

My goal exactly, and my concern is with how to do that while still 
respecting the needs of the underlying networking (and in my case, a 
large amount of interaction with a database).

I'll be very interested to learn more about the melding of the two 
paradigms.

One question: I had the impression that Stackless is mostly an academic 
exercise, sort of a proof of concept.  Is this wrong?  How stable, 
portable, etc. is Stackless at this point?  Is it a reasonable choice 
for a commercial application?

I'll try to be patient.  8^)
