Not 100% sure what's going on with the network between here and there.  He's on a Time Warner or Comcast residential network between his PC in Colorado and my server down in Georgia. 

He's not intentionally leaving a connection open.  When things go as they should, the entire transaction lasts about 3-4 minutes from connection to disconnect.  From a programming perspective, I'm pretty careful to explicitly open and close connections with the program. 

Any ideas?

Is he allowing the connection to sit idle?  If so, this might represent
a router timeout.  What network hardware is between your machine and
this customer's?
