For the hostage of the files themselves, i suggest a site called Ourmedia. Basically, they will host any and all media. You then give it a little Creative Commons license, decide what people can do with it, and thats it. Hosted forever, with [flashing text]unlimited[/flashing text] bandwidth.
All free and everything. I heard of this site on TechTV or something like that. I plan to use it as a host for the teams movie files this year.
I would totally listen to something like this though. Love podcasts, and FIRST.
