That loader is a good idea.

If you have time, you could add one more feature to it:
A "test-connection-server" and "test-connection-ping"

In a way, that a client can make a quick testping to
the server, to see if the ip is correct and there are
no problems with the router / portblocking.

A lot of users have a problem to set up a server.
And such a quick test can assure that the conncetion works
without having to first start up the engine.
