Well, I didn't want to completely re-implement a HTTP server  
(although I suppose its not tough) so I looked at using another one.   
The bit that depends on apache/mod_python is minimal, about a 20 line  
adapter between mod_python and what twisted used to provide.  So if  
you wrote your own http server it would be a reasonably straight  
forward task to do.
I might actually do this, the dependance on apache is a pain, and I  
think xend has its own http server in it atm.

The primary reason I choose python is because thats what we use in  
cambridge, and its what all the other tools and written in ;-)  Also  
it lets me call straight into the XendClient.py stuff, which  
simplifies it greatly.

I seem to remember somebody talking about one, I'm sure somebody else  
on the list will be able to respond to that. If not I'll ask about on  
monday.

The mod_python website has all the info on getting psp up and running  
quickly, just three lines in a config file worked for me.
