Technically, browsing is built on top of the nbt (NetBIOS over TCP/IP)
protocol.  It uses the NetBIOS Name Service and the NetBIOS Datagram
Service.  It does not use either the NetBIOS Session Service or SMB.  That
is why reading a browse list is essentially an overloading of the smb://

Yes, that is one way to look at it.  I personally agree with the
distinction.  W2K SMB (aka CIFS) uses port 445 while NBT uses UDP/137,
UDP/138, and UDP/139.  Even though the SMB messages themselves are very
similar (the same in most cases), I would agree that smb:// and cifs://
are distinct.

That's the overloading we are doing.

Yes, and an interesting conversation.  These issues are certainly not 
obvious and do require careful thought.

What a long, strange thread it's been.
