There is new 1.1 bootcamp with iSight support on Apple site. Perhaps the iSight drivers could be used in Parallels? Can any of the Devs comment on this?
If the drivers are there it may work with the current Parallels USB infrastructure.
Someone who has enough space on their Mac (I don't) should extract the drivers and post them somplace where we can get at them
The only problem we might run into is the dreaded "wait 5 to 10 seconds" thing, being that Mac OS definately has a hold on the camera. Perhaps we can get lucky and have it work in Parallels when the Mac is not recording...
if you install Boot Camp 1.1 on OS X, your built-in iSight will be updated to version 1.82 and XP in Parallels Desktop will not be able to detect and install driver on the built-in iSight anymore.
