Subject: P4P, PVA, and PyQt

I'm looking simplify usage of my P4P python bindings for PV Access
from within a Qt event loop.  The value add is in handling the
threading issues involved.

It would be helpful to me, who doesn't do much UI work,
to get some feedback from those who do.

My scope for this is entirely plumbing, so no UI widgets are involved.
The goal is an API to deliver PVA data structures, or errors, to a Qt Slot.
Actually rendering this in a pleasing way is something I'll leave to
more capable individuals.  (who, being flattered, should go have a look)

I have an example, which might be a good place to start looking.
