Interesting project and I hope this will prove to be a great resource. And as you say, not just for kids, for adults too. We frequently get people asking here where they can get hold of some footage so they can learn or practice editing. This seems like just the thing (OK so they're normally after free, but as these are shot specifically to be edited together, the more "serious" budding editors/filmmakers might go for it).
I also like the idea that people can post their finished film. I could see competitions developing and if this takes off, there's no reason why you shouldn't expand the number of clips/sequences with add-on packs and possibly turn this into a money making venture - enabling you to re-invest in more facilities etc etc etc.
A few questions if I may.
1. It's not clear from your post or blog what is on the EditSense DVD. The text implies it's a bunch of clips which can be edited together to make complete sequences. So far, so good. But if that was the case there would be no need for a Mac/iMovie version and a separate PC/Premiere version. Can you expand on what's included (and does that therefore mean it can't be used with AVID, Pinnacle, Vegas etc?)
2. Licencing. You state the clips can be used for private use, non-commercial projects. Are people free to post their completed projects on YouTube/Vimeo?
3. Licensing in schools. How are you intending to handle this? (I work in IT and look after three schools so my question is not entirely hypothetical)
