Decentralized dropbox over Freenet

[sanity]

Unison is an open source dropbox replacement that works over ssh to synchronize files and directories. It should be straightforward to build something similar on locutus that's even easier to use, something like:

$ freesync share code/freenet/locutus
code/freenet/locutus now shared, secret token: MFZWIZTBONSGMYLTMRTGC43EOZQXGZDWMFZWI5TW

On a different machine:

$ freesync add MFZWIZTBONSGMYLTMRTGC43EOZQXGZDWMFZWI5TW Documents/code/locutus
Directory synced to Documents/code/locutus

And you've got a cloudless dropbox just like that.
