After a lot of disappointing replies from Philips concerning drivers for there WebCams under OS X, today finally this email:
--snip--
Unfortunately, at this time there are no OS 10 drivers available for your
camera. However, we have been told by the engineers that they are at work
on the drivers and they will be released at
http://www.pc-cameras.philips.com. No estimated time was given.
For further assistance please contact tech support at 800 835 3506.
Please refer to the above case number. Sorry for the inconvinence.

So, at least, they SEEM to be working on them.
