Q: Present to 100 ipads control from MBP

I'm looking to present a keynote to 100 iPads.  I'd like to load the keynote file on the iPads and send a signal telling the ipads to advance via a perfect cue system (keynote and MBP).  The keynotes will contain builds and HD video, hence the reason for loading the file vs a "screen share".  The 100+ iPads I'm wanting to use will all be owned by us, and on a single wifi LAN.

The software would need to tell the iPad that it is on (for example) slide 33.  Not just a simple advance.  This way, if an ipad got out of sync because it missed the "advance" command it would come back into sync on the next "advance" not just advancing forward from 1 wrong slide to another.

Ideas?

Thanks!
