This is some seriously innovative thinking. I want to support it's development.
*Update*- I first read about PlaceSite when I was going to a Drupal meet-up in San Francisco at a co-working space called PariSoMa. People rent out access to this loft type space that has internet access, a kitchen, a cool vibe, and they work on their own projects. Sean Savage, the guy behind PlaceSite is a memeber of that working community and I was interested in meeting him there. But I found out that he wasn't there and someone told me that he didn't think Sean knew too much about Drupal. So the advocate that I am, I emailed Sean and told him I was interested in talking about PlaceSite and he should come to the next Drupal Meet-up at PariSoMa. He said he'd be there unless he had to be out of town for work.
