Hi Damien and Chuck

Appreciate for replying on this.

I want to ask from the client, eg. where do you want to go?, If north, I want to forward to the north server, if south, to the south server.

I need to get developed something probably similar to the Proto Balance (http://www.protonet.co.za/whitepaper.html).

It says "connections are transparently forwarded to an instance chosen by Proto Balance". I want my daemon to make that choice.
