[MLB-WIRELESS] Using VPN's over Internet to link disparate Melbourne Wireless nodes ?

[Ryan Abbenhuys]

I believe this is what WAfreeNet do initially with new clusters that don't
have a wireless path to the main network.  Of course it's a major bottle
neck so it's only temporary until a wireless path can be established.
