I tried creating a BoxCrypter (1.5.409.147) volume within Bitcasa (1.0.0.5) today, with syncing between three Windows 7 computers. I synced about 3.6 GB of images, and the MD5 checksums matched on the three computers, so it appears that this combination is now working. I'd test it more before relying on it, but so far it looks promising.
