The entire NBT layer could be placed into the kernel.  I would see, 
perhaps, LMB, DMB, and NBNS functionality in a daemon but the essential 
parts of the NBT layer are trivial (in comparison with the rest of SMB) 
and could definitely be isolated out.  This would not impact SMB since, 
once the NBT Session is established, the NBT SMB packets are identical to 
naked TCP tranport-ed SMB packets.  They can just be passed through to 
whatever piece handles SMB (even directly to the existing smbd, thus 
allowing kernelization in stages).

The only issue is in any interprocess communication that Samba currently 
does between smbd and nmbd.  I think that's isolated to LMB and DMB 
activity, but may be wrong there.
