We've been working on doing this here (to make booting diskless win95
from a unix machine simpler).  What has been done to date is full llc
(ieee 802.2) support has been added to the freebsd kernel (done by
John Rochester) and a somewhat simplified netbios protocol layer has been
implemented in user space (simplified as it assumes at most one netbios
session per host - no multiplexing multiple netbios sessions over single
llc session).  Samba (1.9.17) has been hacked to use the netbios layer
(most changes were to keep it from writing the 4 byte packet length
at the start of SMB packets).  Everything appears to be working fine
(can browse a share, copy to and from a share, execute programs, etc.),
but more testing needs to be done, and the netbios layer has to be moved
to the kernel.

The netbios protocol I'm using is based on an IBM doc (SC30-3587-01).
I've been wondering why microsoft calls it netbeui - I suspect it is simply
a marketing thing (maybe IBM owns `netbios'?).  Does anyone know if microsoft
has changed or extented the protocol?
