My thought is that if roomnicks are to be treated as generic  
resources, then we should rethink the idea that resources are not  
visibly meaningful to the end user.  (In most cases, I'm in favor of  
the resources being visually meaningless, but the same rules do not  
apply to roomnicks.)

Otherwise, I think we may want to come up with a separate 'visually  
identifying resource' profile which is basically a case-insensitive  
resourceprep, and use that for MU-C roomnicks, cooperative-browsing/ 
virtual chatroom roomnicks, and so on.
