It's still pointless. The current key-system is a low tech, simple system with few associated costs and no major pain points. It's also a system that is strongly in place already. The Lockitron is a complicated system with many moving parts that will break every now and then, and that has no clear target market, and it's more expensive than current systems.

If the makers get it to work, I'd be happy for them, but my estimation is that it's going to be dead in a couple of years.
