But it doesn't matter (at least to me).  The scenarios I want to support don't
include building a pyz on my Linux machine, giving it to you, and having you
able to run it natively on your Windows machine.

There are lots of interesting use cases we could still support.  I could build
a single-file application and deploy it into my OS's system archives.  I could
deploy that thing into my platform's app store.  I could hand it over to a
colleague running an identical version of the OS.  I could deploy it into my
data center.  I could install it on my phone.

Don't discount sys.executable to quickly. :)

Cheers,
