Thanks for the heads up. I'll try to compile coriander, but it looks like I may need some dependencies and it may take a while to compile them.
In the meantime, how's your french? The coriander website has a link to a whole page devoted to iSight, but it is in French =(

Note that the bash script is not translated well, but is perfectly visible in the original french page.
I'm not sure if this gives you the information you (and I) require.
