I'm interested, as I said, because I want to document stuff like this.

Assuming that there's only one name of the required type.  What happens if
the server is a browser for multiple workgroups (question remains--is that
possible?)  What happens if the server offers virtual servers or aliases?

In theory, remember that NBT is a virtual LAN system and that it emulates
the old PC-LAN/MS-Net system, it should be possible to run multiple server
services, each with a different name, on a given host.  The name is the
complete address of the service, so it should not matter where (on which
host) the service is running.

That's theory.

In practice the defacto standard implementation makes such things
difficult at best.

I'll dig into the details as I learn more.

Not sure I follow but there are known gaps in my knowledge which I'm 
desparately trying to fill.  ;)
