This is an awesome concept. How do you see this working across several rooms (if you've thought this far)? This would be great for when I have ideas in the shower.

The appeal of the lightbulb form factor is that you can mount it in a portable base to move it around the house; or in a fixed socket for broader room coverage.

It's not mentioned in the piece, but for the latter I don't see any technical obstacle to having several of these in different rooms in the house, or a couple in the same room to augment coverage.
