I don't know if your nickname here is related to the minecraft project, but : for me it reaaly deals with appetite for destruction here ! ;-) Very interesting.
For me this would be complicated to dev with Away3D, mainly beacuse of the performances needed to display all the scene's cube with an equivalent to Java perf., even if Away already has the tools that would make it possible. But with smaller area to search and destroy that could be done !
