Hello Maxim,

that’s answered quickly:

> does it require its own .pyc files?
Yes, .pyc files are implementation-dependent, as their name suggests
(module.implementation-version.pyc).

> Does it dismiss CPython's produced ones?
It won’t look at them.

> Can we not point it to consume our existing Python libraries (it's
> different sys.path suggest differently), etc.)
Technically plain Python modules should “just work”, but C extensions
must be recompiled, so usually it’s safer to run setup.py using PyPy and
install into a PyPy-specific site-modules.

Cheers,
Lars
