Only reason I'm not so keen on leaving it running on the home PC is that there are curious "little" hands at home that like to push buttons, flick switches, anything that they are not meant touch in other words.

Might not be a full blown server I am after, I think its more the VPS you can hire for lower monthly fees, like the one linked to by The Ocho.

Thanks for the heads up though about country restrictions, so will definitely check that before I go ahead with any hiring or buying.
