 Thanks Tom for the info, I had remembered twisted being removed but  
hadn't realized that XenSV had been since updated.  A couple  
questions though...
    Why not decouple the interface from Apache (as to require only  
python be installed)?  I am not sure of the performance advantage,  
but it should reduce the memory requirements for dom0, allow for a  
slightly smaller disk (negligible), and make installation easier.
 
 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 think this is what you want:
http://docs.python.org/lib/module-CGIHTTPServer.html
 At some point, I'd like to remove the HTTP server Xend is using and 
replace it with SimpleHTTPServer.
 I might actually do this, the dependance on apache is a pain, and I  
think xend has its own http server in it atm.
 
   Similarly have you looked into writing XenSV in C?
 
 
 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.
 
 Yeah, until the store is more complete, tools pretty much have to be in 
python.
