I'm not quite sure how to ask this but are there any various programs out there that allow multiple users to log on to a program via the internet, say photoshop and work on a project together or watch what the other person is doing?

There IS a program that can record what someone does in photoshop and recreate whatever they were working on. If you wanted multiple users to use it, you just stop doing something in the middle and send the project along. I don't know what it's called though, sorry.

I know Windows XP has "program sharing" capabilities with MSN but I've never tried it out myself.
