A fully compliant JVM written in Js. Doppio is the most advanced one that I know of. http://int3.github.com/doppio/
Once complete, it will become instantly redundant, because the non ms browser vendors will put jvms back in the browser to speed things up.
And that's a good thing! This whole js only thing for the web is dumb. At some point in the future, it could be 0 years, 20 years, this will come about and we (you) will all slap our foreheads and go...OMG, we could have been writing our web apps in language (insert favourite here) X this whole time? What were we thinking.
JS is being compiled and minified and closured away. JVM is open, it's bytecode. It can run anywhere. Let's let go of this fiction that its somehow good or more open to have a single client side web language.
