Remote control

I'm looking for some compact camera supporting remote control, that is I can
shoot from my PC and I'm able to see the camera display on the monitor.
Remote control was supported by Nikon Coolpix L1 and some other models but
now Nikon does no more release this sw and indeed does not support it under
Vista.
I read many Canon cameras support remote control but I discovered they are
only Gx series (rather costly) and A640 (an old model) - I hope I'm wrong...
Alternatively a remote shooting device (wired or wireless) would do but it
seems they are foreseen only for reflex cameras.
Or I could costlessly shoot by Windows' feature of image acquiring but it
seems PTP protocol support is required and it is difficult to find such info
for the various models
Any idea?
