 I've been going over the ZEO docs and it looks pretty cool. In fact it 
would solve a few minor issues I'm having with one of my apps. My concern, 
however, is that my main app is *very* write intensive when it's running. 
Methinks a little benchmarking is in order...

 I've tried Tkinker and really disliked it. wxPython, while far from perfect 
feels much better...maybe doing something like pydoc with using the built in 
web server is in order. :)

Thanks for the input.
