Well, you CAN do this, but then it is necessary to use the "remote browse 
sync" and "remote announce" parameters on both systems to gain cross-subnet 
browsing and name resolution capability. You will likely find that Windows 
hosts will register with only one WINS server - that is one of the key 
reasons for the advice that is in the man page and in the HOWTO book.

You COULD (likely will) have broken NetBIOS name resolution, with the result 
that windows clients can panic and blue-screen.
