Hi All,
thank you as usual for your kind suggestions. I was starting to
believe I could use Karsten's suggestion, but it seems that
unfortunately pysqlite does not have any LISTEN/NOTIFY mechanism,
unless I am completely wrong... I don't think I can switch right now
the database backend, but I will investigate also this possibility.
If I can't change from pysqlite, I'll probably go for David
suggestions, that looks very nice and very well implemented (and also
extremely well commented).
Just to close this thread, if someone is interested, I have used
David's beautiful MessageServer class (and I have also stolen the
ChatWindow 
) to make our PCs aware of each other while my
application is running on those PCs. The central server is on a Linux
machine while our PCs play the "client" role. We are only 6 reservoir
engineers, so it's not that high traffic, but the solution is
incredibly elegant.
Thank you David and thanks to all wxPython users that shared their
thoughts on this issue.
Andrea.
