Open Source Box.net using S3, RackCloud etc

Wondering if anyone knows of an open source project which is basically box.net but using S3 or RackCloud or others. 开发者_JAVA技巧I have googled like I have never googled before and couldn't find anything. Tried different terms etc ... nothing.

I would love to host my own solution instead of paying $25 per user per month. We have a lot of users ... 100+ and yes they give us a discount but still pretty expensive.

Seems like something easy to build.

Thanks for your help!

And....2 years later :)

Adam,

Your ninja searching skills are strong :)

No open source solution exists as an alternative to Box.net. They have a solid and unique product for businesses and it would take a ton of developers to build from scratch the type of functionality that their product offers.
