> So I'm right in that the project is not public/not open source at the moment, otherwise I'm sure you would have given a link to it already or at least more information about it.

it is, it's called Pharo. so again your wrong. it's maybe in our heads,
luckily one cannot put copyrights there yet ;). The idea IS the information.

We plan, somewhere in the glorious future we will have a great system.

I work fulltime as a PhD so no time to do any closed-sure projects aside -
it's that simple ;)

yes you got it right, that's why we plan to use it for runtime 
compression of more or less in-frequently used ASTs and Source code in 
the image.

But again that's future talk, I know.

if you read carefully I corrected myself to only bundle the VM with the plugin,
not link it against, so yes.

we did and if we ship a future PharoXX with it at some point we need to have
it somewhere close to the VM.
