Another idea...

[Dan M]

I have an Idea. I think that there should be a module for flying online, and the hard part to make, a thing in it that
enables you to talk to a person for atc. Must Have for virtual space program!

So you think, the chat thing is harder to realise than the online flying module?
There is already a module that allows online flying and it even includes a chat function (if I remember right),
but it's not sophisticated enough yet to allow serious online playing.
