You've got to think outside of the box a bit. They could use this for remote interviews that entail live problem solving. It could really help cut down the number of candidates that require in-person interviews if they live in another state.

That just sounds like a different product. I wouldn't want anyone to be able to pop in and watch my interview.

Also, are you sure that it does already exist?

I think we'll end up with some planned and edited screencasts, and some "live coding" streams that are great (with 95% of the live streams being dull.) So there would probably need to be some kind of reputation system or way to look for coders who happen to be interesting in this format.

There are some really good screencasts out there -- I watched some of Kent Beck's Test Driven Development videos and learned way more than I did from the book. (http://pragprog.com/screencasts/v-kbtdd/test-driven-developm...)

The point isn't to sit and watch a 10-hour coding session. Even if such lengthy things are available, I imagine the most benefit would come from just watching a random 5 minutes of a bunch of different people's styles and learning from their basic approaches.
