Just found an interesting post about WOL (Wake on lan) over the internet, now that sound kind of useful 😀

Update;
I have “installed” and tested this, but so far sadly without luck :-/ I will hopefully have time to do some more digging in the near future, but I am a bit sceptic, when the PC is off it does not have an IP!? It may work if you have an ADSL modem but with a router I can’t really see how it would work.
