I really like the simplicity and overall fairness of the plan. The only thing I wouldn't like (and it could very well be that way for technical reasons[1]) is the part where only current employees get a part of it. I understand the idea behind that but if someone were to do fantastic work for them for over 5 years and leave 6 months before Jason Fried and DHH change their mind about selling, that employee might feel stiffed. Instead, I could see a system where you earn units while you work there and lose them for the time you don't work with them, at the same or different rate. Say you earn 1 unit per year worked but lose 2+ per year non-worked. But, you know what? It's their company, they do it however they want to :) and considering they have no obligations to put that in place, it's hard to argue. [1] e.g. maybe it's a pain to pay somebody anything once they're not on the payroll…
