Actually, PTP has an specified command (getProperty / setProperty) and
IIRC Image Capture SDK for 10.4 had a functional equivalent.
Unfortunately
- ImageCapture grabs the few default properties it knows about at
device connect time and caches them
- Leopard IIRC deprecated the get/setProperty equivalents so one has
to resort to PTP pass-through
- Last !least Canon (in contrary to Nikon) uses custom commands to
access most properties.

The protocol will definitely be PTP, so one has to reverse engineer
only the transfered data. While it's trivial for most tasks, I
couldn't get it to work yet for live video from my D300.

Actually, it _is_ better. You really should try the (10.4) Image
Capture SDK samples. Just don't waste your time trying to manipulate
shutter speed / aperture etc. with it.
My comments above regard _full_ control of a DSLR, like the 80
internal settings of a Nikon D80 or 100+ of a D300 DSLR
