I'll give that a try! - I've never used the multiframe tool before...
I was a little worried that there would be too much content on one page to keep track of. It'll be used for a live event where changes to content will neeed to be quick and easy.

Edit
I've given it a try and I can't understand why I've never used it before!
It seems to do exactly what I need.
Now the only problem is getting the publication to run smoothly... its going to be projected using 4 projectors through a watchout system. Publication size is 3463 x 768 pixels !
