Re: embedded python in c++ packaging
The Python byte-code files are already pretty dense, so compressing them further is unlikely to work if you try to put them in a zip.

Re: dream hardware
A Cray? What are you trying to do? "dream" hardware is a very wide question.

Re: Python Written in C?
The OO overheads for C++ are almost non-existent.
