I run a google group called Business Bootstrappers. I don't have a unified theory, but I did forward the links to this article, discussion and Startup School to it, which is part of why I asked this question. It has no goal of fostering what people call "lifestyle businesses" (a term I am not fond of http://micheleincalifornia.blogspot.com/2014/03/i-love-lucy-...), but it does have a goal of supporting businesses that aren't specifically looking to take VC funding.
