I mean to say a11y libraries, anyways you got what I try to convey :-)

I created this for Mago project. Hudson runs as root user (atleast in
Ubuntu). So, I need to create 2 different scripts, a11yservice.py will run
as regular user and a11yclient.py will run as Hudson user.

If a11yservice.py gets started when the Xvfb session starts, then you can
run the test as you expect, by invoking your script with a11yclient.py.

Hope this helps.
