The IP address of the client need not change - if a VPN is used...

P.S. Humph - while (as far as I can tell) I had mobile connections 
working from my desk - today, trying to use the connection in real life, 
it failed... what's more - my adoption of Blueman prevented my old

Hurumph - it is rather temperamental.
