I think this is very promising, as a business owner I have a desktop in the office and a laptop for the road, it makes for a secure way to sync the "customer-folders" between both PC's and saves me from getting my laptop out because there's a file on there that isn't yet on the desktop ... While Dropbox is a good tool, I'd be more at ease the files are transfered securely/encrypted... And not resting on some cloud server, call it paranoid or whatever you want... Yes, I could use Truecrypt or whatever, but this has the "approachability" factor in its favor ... And no I'm not saying Truecrypt is difficult, I'm speaking more in general... I will probably test this out.
