Well, I sat in the dark for an hour tonight and decided that I should report my findings:
Here is a picture of me on the couch with my beer and baby monitor:

All in all I think this was an “ok” experience. I’ll do it again next year - hopefully start a trend. I was thinking that it would be really cool to be in a restaurant or pub for that hour - with candles lit and a bottle of red (maybe a bottle of white), and some live acoustic music playing? Sounds nice.
UPDATE: Looks like Google got in on the action too (see screenshot here).
