I recently looked into ParticipatoryEconomics? and even though it looks interesting, it has the following important part missing:
Many a utopia has been envisioned, but few came to pass. The problem is often, that a viable path from the here and now to the proposed utopia is missing. Granted, the proposed path is often called 'revolution', but that is like saying we heat the pot and hope, that after cooling the result will be a crystal (but in fact the previous state may be equally or even more likely).
Also the utopia has to be stable under perturbations (small inner and large outer ones). A utopia that falls into the middle ages after a large earthquake disrupts its smooth flows is not worth much.
An example of a successful (even if partial) ReachableUtopia is the GeneralPublicLicence. It is embedded in the existing system in the form of a contract, but is constructed in such a way as to grow by placing more and more under that contract (that's why it is called GeneralPublicVirus?) the idea is that it grows until it encompasses everything, thereby making the original economy empty (no other contracts remain and all corresponding rules can be disposed of).
In short: it is not enough to show a better system, one also has to make plausible, that that state can be reached and is stable.

This fabulous piece of writing by Alexander Schmemann (from "Between Utopia and Escape") seems appropriate for this topic:
And what about the GPL example?
I don't think of it as a utopia, it's just one of the many forms of contracts between providers and suppliers in the software economy. And because of its viral nature, it's not quite as popular in the OpenSource movement as it was in the beginning. I've put my WikiChangeProposal project under Apache license without loosing one second of thought. In the end, people vote with their feet and human nature is thankfully so diverse that in a normal world (with free speech and individual freedom), no utopian project will gather the needed super-majority to be imposed on a societal scale. -- Costin
Any reachable social system will have to meet the requirements of an EvolutionarilyStableStrategy.
That's true for social systems in general, but to be more than that, and specifically, to be a utopia (like the ParticipatoryEconomy? example, or the communist society as envisioned by Marx), the EvolutionarilyStableStrategy has to shoot for the global maximum while avoiding being stuck in a local maximum. Or this is, if not impossible, at least extraordinarily unlikely using normal means. Hence the need for "revolution", and once tainted with blood all utopia are irremediably corrupted, just like the bears who once fed on human blood will always try to eat humans and have to be shot. That's just the side-effect of human nature.
My statement above implies that any reachable social system (including any imagined utopia) has to be a stable local maximum (part of the requirements of an EvolutionarilyStableStrategy). It has to survive exploitation by opportunistic populations.
