It's not too hard to find one. Unless you're completely anti-social you probably have at least one tech-savvy friend that can understand the need for this kind of setup. Even better if you have more than one friend (hopefully not too be an "if") then you can have a "round robin" approach with a group of friends. An open source (so the crypto can actually be vetted) version of BTSync[1] would be great for this.

Haha. Yes plugging in random networked boxes at the office might arouse some (just!) concern. When I wrote that piece I was thinking specifically of my company as I'm the boss :D
