I'm really not sure this is a smart idea. In.solit.us (quit it with these domains already!) is a service for public file sharing - you can also share a file with a select group of users, or send a link to the file via email. All you need to do is upload a file using the web-based uploader, enter a short description and decide whether you want it to be public or not. This seems highly, highly problematic: it seems users are free to upload copyrighted content or files infested with viruses, spyware and all kinds of nasties.
