Here's the beginning Estonia wiki subject page at WUaS - http://worlduniversity.wikia.com/wiki/Estonia - which is also the beginning of the MIT OCW-centric Estonia World University and School, eventually in the Estonian language (which is also accessible here from the main, WUaS Nation States' page - http://worlduniversity.wikia.com/wiki/Nation_States).
And here's the beginning of the Estonian language wiki page at WUaS, - http://worlduniversity.wikia.com/wiki/Estonian_language - for open teaching and learning, and which will eventually be in both English and Eesti, and other languages - accessible here from the main, WUaS Languages' page - http://worlduniversity.wikia.com/wiki/Languages. Not knowing Estonian myself, I added the Quaker page in Estonian here, as well as some language-learning pages, as beginnings. And you'll find MIT OCW at the top, with MIT OCW translated courses, as well, but not yet in Estonian. Do you know of any Estonian language OCW?
Are you on the wikidata-l or wikitech-l email lists, for developers of the new Wikidata database, written with Wikipedia's 287 languages in mind, by any chance? WUaS would like to move there in the future, and for all 7,105 languages planned for WUaS.
And would you like explore co-writing a WUaS grant together?
I'd be interested in talking with you further about building interactive virtual worlds (as an ethnographic field site, for a second book I'm writing) in something like, for conceptual purposes, OpenSim/Second Life with Google Earth in the Oculus Rift goggles.
