(Disclaimer: I don't know much at all about the current standards of encryption)
Is this security not already standard, and not practiced by companies like Dropbox? As a side note, I like the collaboration aspect and one-person-per-paragraph is a pretty smart idea!
Edit: To those downvoting, sorry, I'm just curious and I think some of us were unaware of the differences between Airborn and other services, which I've now learned can still view your data
Most "encrypted communications" means that no unauthorized third parties can view the data as a result of the encryption. However, even if Dropbox stores your files encrypted, they still have the keys to those files and so could be coerced into decrypting (them through a warrant, for example).
