[Interest] porting a tcl gui to qt

[Josiah Bryan]

I've written a basic generic QVariantMap server/client set of classes. I
know this code is probably rather rough - might just be better used as
an "example" or a starting point on writing your own. Take it for what it's
worth, here's the code:

https://code.google.com/p/livepro/source/browse/trunk/varnet

The "server" end would use VariantMapServer (derived from QTcpServer) and
connect to the "receivedMap(QVariantMap)" signal to receive input from
clients, and use the "sendMap(QVariantMap)" slot to send data to the
clients.

The "client" end would use the "VariantMapClient" class which offers the
same pair of signal and slots to send/receive QVariantMaps.
