This article resembles the recent posts about using git on Dropbox - I wonder if people actually tried this for a longer period, because it just doesn't work, unless you mount the volume only one machine simultaneously and always sync after unmounting (easy to forget after mobile use).

Major lossage ensued when I found dropbox gave me multiple versions of that truecrypt volume.

I program out of my TrueCrypt volume while in Windows, unmount it, and let it sync. It's a super-easy backup, and DropBox is the only one I've used that handles a 1GB file correctly, and it does it without a hitch.

Worst-case-scenario is you do cause a collision, and you just mount both volumes at once and copy stuff to the one you want to keep.

I use Dropbox more like a thumbdrive for temporary transfers and I like to have the warm and fuzzies that my data at rest is protected with strong encryption.
