Luke, we're talking about mapping DNS name to NetBIOS names.  The idea 
suggested was that nmbd should reject NetBIOS names that do not conform 
to DNS syntax.  The only non-alphanumeric character allowed in a DNS name 
is the dash.

If you restrict your NBNS server that way, is it an NBNS server?  If you 
don't register group names, will the machines be able to find the 
services that they are looking to find?  I don't think that this is a 
functional solution.

Of course, my stance (having tried too hard to make it work) is that
NetBIOS names simply *do not* map to DNS names and vice-versa.  *Unless*
you are using the Level 1 encoding *and* scope as described in the RFCs.

Of course, no one does that.

If a machine's DNS name happens to be the same string as one of the
NetBIOS names (sans type byte) that it has registered, that's nice. 
Trying to build a formal mapping between the two is neither practical nor
