There are few, if any, restrictions.  The RFCs say only that the name may 
not begin with a '*'.

That's one way (though I think I see a small bug).  The other is to use 
an escape sequence as is currently done in URLs.

This, and the misconfigured network problem, are both inherent in the NBT
system.  The misconfigured network problem was identified by the RFC
authors themselves.  See:  RFC 1001, Section 10.  The RFCs also deal with
the issue of otherwise-illegal characters in the NetBIOS name by encoding
the name to an always-legal form.  We are not dealing with anything new

So we can't look at these as major problems, just annoyances to be worked
