I would absolutely love to help realise the dream of establishing a virtual museum to educate the world about technology in a physical, obvious and intuitive manner.
I have a proposal for the community. And it's rather tough to swallow but bear with me. I suggest you scrap the idea of doing it in Minecraft and instead help develop another technology in which to create the museum.
There are a number of reasons I suggest this but I will outline the most important.
I feel Notch is heading in another direction with the development of the game than the direction we need to realise this dream. For some time he will be focusing solely on removing SMP bugs and fixing minecarts rather than implementing technology to help facilitate the creation of an online virtual museum. The development of Minecraft is not open and driven by the priorities of Notch himself rather than those of the community; on occasion Notch blatantly ignored the priorities of thousands of people who have PAID for the game.
Secondly, whilst primitive components of electronic circuits are indeed available in minecraft and they can be used to construct complex devices (as you have shown), constructing gates and other simple components over and over becomes time consuming and verbose (needs alot of space) and I believe this will make understanding the contraptions in the museum too difficult. Instead our platform can provide more complex components like those available in Wiremod (http://wiki.garrysmod.com/?title=Wiremod). There's no reason people cannot drill down into these components to understand their internal workings but I feel when trying to understand a CPU there's no reason to overwhelm someone with the internals of thousands of logic gates. Alternatively, they should be able to have an overview of the gates and their arrangement rather then their compositions.
Instead we can develop an engine in open-source, standards-based web technologies (HTML5, WebGL, websockets, node.js, etc) for the museum to be built upon. This engine or platform can live on the internet (as a website, much like minecraft classic) for anyone to login at anytime and begin creating their own and understanding contraptions others have built.
I have made some progress (http://www.youtube.com/user/pyrotechnick). It's very early days but I believe with some help we can draw enough attention to the project and accelerate development so that we may realise our dreams on a reasonable time-scale.
Please let me know your thoughts...

P.S: The project has been accepted into Kickstarter (http://www.kickstarter.com/) but as an Australian citizen I am unable to accept funding until I have a trusted American contact...
