I like it so far. The site does seem a bit empty (expected for 4 hours), but there is nothing inherently bad about the design. A few comments about using it:

1) I think it would really benefit from displaying the expiration date / number of downloads left. Right now, there don't seem to be any pages for the files, but being able to see what I'm downloading before doing so would also be great.

2) You might benefit from giving some shorter links. This seems like something that would be used on twitter or the like, and links that take up over half the allowed characters could be detrimental to adoption. One could use a URL shortener, but I'd personally like to avoid more indirection than necessary.

As for monetization, my first thought would be to sell extra downloads / longer time. You could also try selling larger file sizes.
