Hi Guys,
We're actually considering allowing people to download, but there are intellectual property concerns with that (if you download someone's work off our site, and upload it to a million other sites, it gets in the way of that person being able to profit from our site).
In the future, if we can ever afford the technology, we'll consider purchasing a tool that will convert files to quicktime. Whether or not it is allowed for download would be an option of the user.
