Computer Conrtrol of camera - Is it possible?

[McBarset]

Currently a Canon user, I often use my camera tethered to a computer (and mains) for studio photography. This includes image preview, adjusting camera exposure, taking the shot & downloading image to computer instead of writing to card.

I will very likely be buying the Sony R1 and although it may not be compatible, I'm wondering, as I can't find any mention (on this site or elsewhere), does any one know of any suitable software that works with existing Sony cameras.
