It sounds like a good idea...
What you can also do is start up a thread with links to freediving videos and ask the admins to sticky it or something.
I have used the search option and found little results for videos
... However if I were to look around google video I can find a few that are somewhat decent.
So if you don't get your wish of there being a specific area try creating a thread for people to post up freediving video links.
