I don't presently have a great overall solution for making downloads broadly available... My vids are on critical commons, and if you have an advanced user account there you can download, but that mostly means other vidders can download them, not general users.

absolutedestiny wrote up a post on a different kind of hosting, but I haven't tried to figure it out.

But the simplest, cheapest way to make a download available for a single person who asks for a download is to upload to Dropbox or Google docs and just send them the download link. That's what I've been doing lately if someone asks for a download.
