Yes, open standards and open access are what we want (as well as ponies). But we don't get them by saying "please".
We get open standards by building open software that implements proposed standards. We get open access by building hardware that can be accessed openly.
Governments and businesses will only join the open-bandwagon once we have demonstrated that it works - and works better.
So open source and open hardware are a vital prerequisite to getting open standards and open access.
