The gates have literally and metaphorically opened for Connected Data today.
This company officially emerged out of stealth mode, is within days of shipping its first batch of devices, and announced $6 million in its first round of funding. Connected Data manufactures the Transporter, a piece of hardware that is "online, but off-cloud" for privately sharing, accessing, and protecting files.
Interesting, but not sure why a simple software solution wouldn't be better. The only use case I can think of is the home or workgroup where everyone is using tablets or laptops exclusively, so this fills the gap with the always on/always connected device that would otherwise require a stationary PC or Mac.
