Yes, I believe that the NetBIOS implementation is a kernel driver in

Well, that's exactly what I want to avoid.  NetBIOS multiplexes many 
NetBIOS "ports" through a single TCP/IP port.  It can also use SPX/IPX 
as it's underlying protocol.

If Samba were written the right way, it would be possible to share 
TCP/IP port 139 with Wine via a unix domain socket, so that applications 
running under Wine (eg. MS Hearts) could participate on the Windows 
network alongside Samba.

Well, at least I would like to have full NetBIOS client functionality; 
access to file shares without mounting them on the UNIX VFS, access to 
Named Pipe endpoints on other machines, the ability to browse Network 
shares, etc.

That would be a good starting point. If we could then go onto supporting 
applications that listen for NetBIOS requests, that would be good too.

Yes, integration is what makes Wine good, so I agree with you here.
