Ooh, that's a good idea. I'm a huge fan of co-ops (not for any principled reason, I just think they're cool). They aren't common for startups of the type we're writing about, but I think it does make sense to discuss that topic. Thank you for the suggestion!
Indeed! The main difficulty is that while we are experts on startup law, we're not in other things, such as co-ops. But we are working on a way to allow others to combine their expertise with our software to serve other markets :)
