Mac mini Core Solo - multiple iChat windows

Hi.

I have two questions that are of interest to me. Thank you in advance
for your answers.

1.) Has anybody used the iSight camera with the Mac mini Core Solo and
done a video chat with 3 other people simultaneously?

2.) Would a Core Duo be able to?

I know the G5's can do this, though the G4 Man mini's are said to not
to be able to.

With kind regards
John
