The above is a simple Client and Server Application pair that just serializes a couple of objects and shoots them across the socket connection. Substitute your stuff for sendObject and recvObject. If you've done this in "C" then this should be sufficient. If it isn't, let me know and I'll fill in the blanks for you.

That's a lot easier than doing it in C! I should have done less points, I thought it was harder to do!
