I'm going to have a crack at running it on an Atom based netbook, possibly over the weekend. Should be enough for the meantime. Thanks for all the help. On a side note, what's the deal with porting a conventional POTS phone number to a VOIP service these days? I've had a go in the past but gave up due to ADSL being on the same line and it went straight into the too-hard basket at the time. This was a few years ago now so I'm not sure if it's still a difficult process or not.
