Possibly this can be partially avoided by providing your own DN Server's IP ?
(dunno precisly how the client would connect to it, but still...)

In plaintext ?

Maybe the use of challenges would be more secure, but i'm not a specialist in
this matter :-(

Would it be good if the client could select several worlds ?
(then the negociation following could use this to get a good WS)

I wonder if it couldn't be more interesting if the client disconnects from LS
_after_ having initiated the connection to the FES. Then, if something goes
wrong, the client could goto 4 directly.
