bind to specific ip

Hi,

as far as I can see from the code, it's not yet possible to provide an ip adress to bind the listener socket to when creating a SocketManager which accepts incoming connections.

Are there any plans to support this in the future?

I'm tempted to alter the source code to provide me this feature.

Anyway, I would like to tell you that you have created a great lib with etwork!

Have fun,
Stefan
