Just FYI, I'm pretty sure the HTTP transport is borked in 3.0 right 
now.  I wrote a wrapper for it a few weeks ago and put a less stress on 
it and it crapped out very quickly.  Since it's off by default, I 
haven't investigated it.

A good approach for management applications is remote ssh.  xm list 
--long is your friend and will give you all of the information you 
need.  Plus, you get authentication/authorization for free.  If you use 
the -S option of SSH, you can multiplex many commands over a single 
connection efficiently (and only have to prompt for password once).  
Just catch me in #xen if you want more info about this.
