BitTorrent first connects out to a central server, and starts the

That's not true.  You can seed a file that you've already downloaded,  
without downloading anything more.

It doesn't accept connections if it isn't connected to a server yet.

Well, downloaders need a way to find you.  If you don't contact the  
central server, how will they know you're seeding?  So yes, the client  
does need to make an outbound connection to some server before it can  
receiving inbound connection requestions.

In any case, I think you missed the joke, which had nothing to do with any  
of the above.

But is it posible to create an applet which can accept an incoming
connection if it's behind a router? And if it's posible, how is
this done?
Also I still don't realy get how Skype does this. When I'm running
Skype
(and I'm behind a router) I have the "use port 80 and 443 as
alternatives
for incoming connections" enabled and Skype can receive incoming
connections (calls).
How does Skype do this?
