Here are bits and pieces of what you are asking for.  If you would
like further details on any of this, just followup...

LM uses a protocol called Server Message Block (SMB).  There are various
"levels" of SMB that are supported by various products from various vendors.
MSNET, LM, LM/X, AT&T, 3Com, MS, (DG).  In short, they all provide different
levels of file/print/ipc services and are compatible with each other.

LM uses the NetBIOS INTERFACE.  NetBIOS, in itself, is just an interface.  It
does not define the underlying transport protocol.  IBM has de facto defined it
with their NetBEUI (NetBIOS Extended User Interface) protocol that runs over 
Token Ring (usually).  There are other protocols, however, that support NetBIOS
primitives.  Some of the more well-known are:

RFC 1001/1002		NetBIOS over TCP/IP
TOP/NetBIOS		NetBIOS over ISO
NetBEUI			IBM NetBIOS

Some others include...

Novell NetBIOS emulation	NetBIOS over IPX
3COM NBP		Skinny NetBIOS (lean and mean but proprietary).

Many other vendors also have proprietary NetBIOS products too.

In general, most of the products can be found under DOS, OS/2 and various
flavors of Unix.  I don't know of a 3COM NBP implementation under
Unix however.

Good luck!
