Yojimbo without .Mac (update)
Via my Lijit stats, I see that quite a few people are coming here searching for a solution of syncronizing or backing up Yojimbo without .Mac.
Alas I don't have an answer. I gave up and signed up for the .Mac service, despite their claimed "right" to snoop through or destroy whatever I put there. I'm using much more encryption on my entries now, that's for sure (and probably a best practice anyway).
I wish there were another answer. Alas....
