3 swf communicating? is it possible?

Hello friends!

I have another question.
I must realize an effect like this site www.2009.it but with a difference.

3 squared communicating but on 3 different swf. I must “pass” an image (like 2009.it) from a squared to another.

It is possibile syncrony 3 or more swf? Yes? with flash 7 or only with flash 8?
Do you now a site with a tutorials or site with this effect.

Thank and sorry again for my bad english.
