Tristan, thank you for pointing out nevow.athena -- I did not know of it. I 
did know
of livepage but I was hoping for something less involved. On the other 
hand, the
ability to freely communicate back and forth between browser and server without
the need for a plug-in is so important that I'm willing to take the plunge 
into nevow.

Kindly let me know if there is any documentation on athena other than the
athena.py and .js modules that reside in the nevow 0.6.0 release, otherwise 
I will
find my way through the source and Twisted-web archives.
