Thanks for the input, Andrew.

Can I disable nmbd if clients use \\192.168.0.1\share style addresses?

And when an smb connection is active but the client is idle, does the client
expect anything from the server? If not, the next client msg will trigger
wake-on-lan and the connection will be fine...
