I don't think it's a matter of getting all schools on the same page at the same time. It's about setting up infrastructure that promotes, sustains and encourages diverse types of schools, many of them public (i.e. tax supported, federally or state chartered) and then going out and recruiting, which means selling parents on these alternatives, as much as would-be enrollees.
If it's public, you should probably be looking to serve a cross-section of the community, certainly not just the financially secure. Students with special needs and many backgrounds will be the norm, including a complement of non-citizens in many cases, sometimes members of visiting families retaining citizenship overseas.
I think the hippies of the 60s, 70s had some of the right ideas, about deliberately forming new communities based on innovative infrastructure (bioneering, permaculture, other ecovillage tech), but these days we don't employ the "drop out" concept, i.e. we're not "leaving" high civilization but trailblazing new dimensions and features thereof.
Some of us are at least part time into Xtremely Remote Living (XRL), where there's a premium placed on learning about energy and sustainable lifestyles. This emphasis on "home economics" may seem rustic and semi-primitive (ala the Amish for example, or ala some parts of Alaska) but we're not necessarily excluding satellite linkups, fat pipes to/from the Internet, lots of flatscreen TVs, dirt bikes, snow mobiles, helicopters and so on.
Into these newly created artificial environments (artificial = using lots of artifacts) we'll weave our relevant curriculum writing, much of it open source.
These won't be the same skills or concepts you learn in Chicago or Detroit maybe. We won't be using any of the text books most kids are now using. But that's OK. We recruit from all over, and just because you're not learning math the way most teach it now, doesn't mean you won't have such opportunities in future, when these alternatives become more widely available, as lifestyle options, to more people. So stay tuned.
The idea with these "company towns" is they're actually nonprofits, closer to charities in conception, but charged with the difficult work of prototyping commercializable new appliances and artifacts, along with new curriculum to go with. Although NGOs, they work closely with the GOs (OSCON meets GOSCON), as well as the R&D divisions of various corporations (the Portland Knowledge Lab is a good example of such an R&D nexus, inspired a lot by Free Geek).
If this sounds a lot like the role the military plays already, in terms of prototyping what's later privatized and commercialized, sometimes for the civilian sector, that's no accident. If you think of the military as an extension of the public education system, then it's obvious that we have diverse, technology-based curricula out there even today.
Project Renaissance builds on this already familiar design pattern, without insisting that military service is the *only* way to serve your country. Some of our top recruits worked their way up the ranks in Hollywood for example -- not the Pentagon maybe, but in some ways just as Darwinian. Still others work their way in through music, via Nashville or whatever.
