Req Put.io

Would love to try this service out, if anyone can spare an invite?

Members don't have invitations. Follow their twitter and if you are lucky you may get one.

Moved to the correct section.
By the way, what's that site about ?

An storage service that lets you stream downloads, apparently.

Nothing else than main page says. Basically a seedbox/storage with some additional features like video streaming or rapidshare downloading.
