Is there any scope to help this project along? I don’t know Smalltalk or ARM assembler so face a huge learning curve in that respect but do know C,C++,C# and Java and x86 assembler many moons ago!

well, when we applied the Cog JIT VM at Qwaq/Teleplace we saw a three-fold improvement in frame-rate, i.e. an application improvement of a factor of three. Certain benchmarks improve by a factor of five, but an interactive application has performance-iontensive activities (graphics) that the JIT has no effect on.

That sounds very encouraging. I won’t pretend to understand it all though! You may have guessed that I’m approaching this from a Scratch running on a Raspberry Pi perspective. What performance improvement would you expect an ARM JIT to make to this scenario?
