G'day Andrew, You need not be unduly concerned about the difference between UDP and TCP, since the extra hop of the WebSocket server will more than cover the difference. Players will be at a slight disadvantage, but now that everybody has fibre to the home, it won't be a problem. New players won't notice. Old players won't want to change. It's a non-issue. Don't let it stop you. You also need not be worried about RSA verification. No server requires it. The server source does not include RSA support. Several clients already exist without RSA support. So go for it. Looking forward to your first implementation. You should post back here once you have something for people to test. -- James Cameron http://quozl.linux.org.au/
