Hello,
just premiered yesterday (Dec. 5th 09) with "Nussknacker" @ Hanover State Opera. Used Two "Player-configuered" computers running one as the Player backstage feeding two cloned projectors (no, we did not do the usal VJ thing. Those two were never to be seen together.) and one as the Manager with the USB extension, ran by the stage manager herself.
We ran several loops of snowflakes and other falling particles (all done in Motion), a series of comiclike speech ballons (synched to the orchestra and dancers) and some backgrounds (mainly one PHG in high resolution we panned over very slowly.

We ran into some limitations of the Player and mainly created some feature wishes for 4.5.1 ;]
The most important thing to notice: If you want to blend layers You'll need Alpha, and that won't work because the data rate will be to hight... PreRoll times where up to 10 seconds and more, and after some shifting and repositioning it came out with only one dropped frame during the whole performance.
