OK - now that we have split the atom regarding what might be the best DNS 
solution, how does this help resolve NetBIOS names within Linux? Have I 
missed something vital in this thread?  Seems I must have.

I'd like to know how you propose to store the name_type info in DNS?

For example, how would you store "MYSERVERNAME<20>" in DNS?  

Next, how will you teach the Windows client to search DNS for that info.  
After all, we are dealing with the NetBIOS name space.
