hi Doug,

I think that the Stage flag you're looking for is '-p <port>'.  See, Stage
is also listening on a particular port, and unless you tell it different, it
will always listen on 6601 (hence your binding errors).  So, each user should
pick a different port and pass it to Stage on the command line.

Btw, this will all get much easier relatively soon.  I've recently implemented
a name-server functionality and the ability for Player to auto-assign ports.
That way, you can pretty much ignore such port management issues.
