Could you create a new section on the website for this and call it Peer Review or something along those lines?
This section would be strickly for people to use a video file hosting website like http://www.streamload.com
to supply the link for the video that they would like to have reviewed by fellow disc golfers.
Granted you will need to ask them to supply 3 links for 3 different views in order to provide the best possible feedback.
This would be a fairly easy way for you to simply add a do - it - yourself technique analysis area. Each new topic would be a different throw from a different person. Any drive techniques you like, you could then grab the video and add it to the actual technique review section.
