Digital movie to visible sphere transfer requires 2 operations
1) huge mathematics for calculations image to sphere, database to
sphere, movie to sphere and so on.
2) make digital image viewable by human eye.

For 1st You need army of students of information tehnologies to
make it ready. May be sphere maping mathematics is open, i am not
astronomer. (Oops http://www.stellarium.org/)
2nd of course is done by dmx X server.

If You can get round 1st, then open source soulution is cheaper.
