I think it sounds like a wicked clever idea.

It also sounds like a recipe for bad-blood in the open source world. It emphasizes owning a repo rather than contributing to one that already exists.

It also seems to push for over utilization of resources. Once you get to say 1-10K installs a multi-tenant solution would probably make more sense. What happens then? Does bushido help you roll your customers into one big app? Even if it's not good for bushido's bottom line?

Don't get me wrong, I see a lot of good and interesting things coming from this. I just also see some sticky situations.
