Who wouldn't be :), but I'm not the one pulling the
strings, I'm just happy that Python was offered as a
language solution.
I have done all I can with what I know of GadflyB5,
but maybe I could do some funky stuff that would speed
things up if I used O9i or PGSQL; I though GadflyB5
would be nice, to have complete solution in Python.
(We're also using Pyro for some things btw.)

True, but we do not plan to cover more than the subnet
addresses we have to our disposal. If they get more
machines, great, but then they can buy a new server as
well.
