Yeah, I have air display, and it's pretty cool. Of course, it's kinda different from a remote desktop since it works as an extended desktop.
I wouldn't want to do "real" editing on a remote desktop - especially on the iPad - screen realestate is just too small, and I've used a few remote desktop apps, the sluggishness overall really doesn't seem (to me) to make for a good way to edit video. JMHO.
