The FolderShare went faster than I expected. It’s well done, the OS X version seems to work just fine (except it feels so important it displays an icon in the Dock and the menu bar). But FolderShare’s basic principle is that you can connect to foldershare.com, type in your login and password, and navigate your hard disk without any restriction, from any computer. Instead of using the client app’s configuration window to decide which folders are shared, which would be as safe as can be, you have to publish your whole disk to the internet — the only thing you can tell the client to ignore is remote Spotlight searches, but not folder browsing. So, yeah, sure, it’s https and the server refuses letters-only passwords, but that thing’s still nothing else than a huge walking security fault. Go ahead, install an antivirus and a firewall, lock your computer, and install a program that’ll share your whole hard drive to the internet.

It’s a pity, because the functionality would really be interesting. (Unlike .Mac, there’s no centralized storage — it’s all peer-to-peer transparent synchronization.)
