So... to me that means that there's no reason why a clause like the 
one Joerg proposes ("you may not distribute if modified to allow > N 
simultaneous connections") would by itself render a license 
non-OSD-compliant.  If that's the case, you're going to find a lot of 
existing commercial companies try to "open source" their applications 
as user-limited crippleware.  Is that what we want?
