I thought about one possibility. It will not allow you to control the camera, but maybe see the taken picture very shortly after it is taken.
It is the cards that wirelessly transfer the images to a PC - I do not remeber the name or have a link.
Those cards,as far as I know, only can handle jpg format and are very slow.
To set up a connection one needs a wireless accesspoint which can be switched to act as a host,which most accesspoints cannot.
Hacks for some boxes exist but performance is weak.
Other cards are desinged to upload images to the internet directly,which is of no use for the studio / home work.
With the SD10 it is possible to transfer the images to a connected computer
right after each shot via the firewire-connector.
It comes up in SPP.
For some reason it does not work with USB.
I doubt if the SD15 will have firewire or the independent dials for shutter and
