It would be great if there were a way to create Sync links; if I could click on "sync:XXXXXXXXXXXX" and have it automatically start syncing to that secret, then Sync would be incredibly easy to use for stuff like this.
I have written a plain text to base64 encoder here : <a href="http://www.getbitcoin.info/assets/misc/base64generator.html" rel="nofollow">http://www.getbitcoin.info/assets/misc/base64generator.html</a><p>Soo.. instead of sharing keys, you can just share keywords and then generate the keys from the keywords. It's just javascript that I based on another base64 encoding example. Feel free to use as long as I get a credit somewhere.
Be aware there is currently a bug where read-only secrets can be used to add files to a share at the time of joining. Be sure to backup your shared folders early and often!
How secure/stable is this? I'd like to run it as a Dropbox alternative to synchronize files between my computers, and love the fact that it's just an executable.
