A version of it is being done all the time in the book industry.

For example, Harlequin books, whom I write for, have online chat room pitches every other month for the different lines.

For the paranormal line I write for, Nocturne, the company bought stories from 3 out of 10 pitches.

The way it worked was, an author was able to send in a short blurb, a couple of sentences to the reader, then she culled it down to 10 people I believe, then those 10 writers went into a chatroom with the editor and pitched. They were told right there and then if their pitch was good, and the editor requested material.

It might have to be more steamlined for scripts, but I don’t see why it couldnt’ work, as long as you got someone ie: producer, agent, assistant that was willing to take some time out of their busy schedules to do it.
