Example with both receive and send

[jkleiser]

If I want to make an example that e.g. sends a message right after every received message, would it be best to have separate classes InUDPClient and OutUDPClient, or would it be just as fine having a class UDPClient that does both receiving and sending?
I guess receiving and sending should be on separate ports, e.g. 6447 and 6448.

From a technical standpoint, using the same socket for sending and receiving is allowed. So from there it's a design question, based on the needs of your application.
