We have Google Hangouts equipment in all our meeting rooms at Square, and use them for many (most?) meetings. They generally work great.
Update: Never mind, I googled it :) very cool. So it's reliable? I'd love to suggest something like this for my organization. We waste the first 10 minutes of every. single. meeting. just getting situated. It's very frustrating.
I think $1k is a bit steep for what they are hardware-wise, but they're still worth it.

Also, given that they're in the process of shutting down the hangouts API, it doesn't really inspire confidence.
WebRTC, on the other hand, seems to have a bright future.
