OK, If you go doewn the GUI route a more efficient solution to
polling at each end would be a lightweight socket interface from
the client to server. I'm not sure which end originates the big
data volumes, but I'll assume the server.
Client makes request to server via socket
Server writes data to database
Server sends response to client to say data is available
Client reads data from database.

Should be more flexible than a csv file although it would work
in the same way.

SOAP is rapoidly becoming the standartd for remote message
passing between different architectures/lamnguages. Its only
downsides are that it is expensive on both CPU (parsing XML)
and bandwidth (XML v Binary encoding). There are a few security
issues too, but you can get encrypting libraries etc now too.

It could be any database that you can access from both C++
and Python. So if you already use SQL Server or Oracle or
DB2 then just use that and the appropriate adapters.

Just some more thoughts,
