It would be nice if you could automatically withdraw funds instead of making me manually watch the balance and withdraw. For example, every day you could send the balance of any account with over 0.01 BTC in it. Because you'd be sending all of the payouts at once you could use a sendmany to save on transaction fees. Sounds like a better idea to me.
Thanks for the feedback, I will work on getting this put in.

Is it intended that it is not very hard to guess links to files you don't own?
http://www.downloadcoin.com/content.php?dist=__&d=__dist seems to be a userID, d is most likely just a running file ID. If I now query all "d"s for a fixed "dist", I should have a list of all files uploaded with that bitcoin address...
How long do you store files, even if they never get downloaded? Is some content forbidden? What information do you log of Uploaders and Downloaders? How do I delete files again, if I want to?
It's intended that it's not too hard to brute force all the different files at the moment. When you have sold a group of files they also appear on the balance page with a download count. There are plans to offer a store with categories and search functionality soon to assist uploaders with sales, you will be able to choose to opt out of this feature and do a fast upload if you would prefer. It wouldn't be hard to throw a random key on files that don't appear on the store to prevent brute forcing hidden files.
