iTwin – split personality, shared data

iTwin, joined together

iTwin, plugged into computer USB port

The iTwin looks like a couple of mating USB drives, but it’s a little cleverer than that. Separate the two halves of the device, plugging them into two separate online computers, and each computer will be able to see and access all of the documents on each of the computers.

And I mean each of the computers. You can either selectively choose to drop files on the drive(s), or you can have it connect all the contents. The iTwin simply enables a secure connection between two computers. And you’re not carrying the data on the iTwin, you’re carrying the connection. The connection uses AES 256-bit data encryption.

Mac users, the iTwin is not for you. Yet. At the moment the iTwin works only with Microsoft Windows XP, Microsoft Windows Vista, Microsoft Windows 7, both 32-bit and 64-bit versions.
