Redboard storyboarding software - anybody used it?

Hi there,

I've just come across this storyboarding software called Redboard that imports models from Maya and then allows storyboard artists to draw over it.

Has anybody here used it in big productions? The demo seems pretty good, but I'd love to hear from anybody who has used it solidly as it's always difficult to know how something performs from just a few days playing around with it?

Many thanks,

jay
