Distributing Python apps

Taking a quick glance at just Python, I don't think your goal of putting
Python + app + data on a single 1.44mb floppy is realistic.

Python installer on windows is 6+mb.

Installed Python is at least 1+mb just for dll's and libs (not including doc
and examples etc.), of which some parts may not be needed by your app.
Additional specialist dll's and scripts needed by your app not included in
that estimate.

In terms of a download, I'm betting that 2+mb for a runtime only including
application bytes (binaries and doc) is more likely.

I suggest a more practical and realistic goal is to plan on a CD
distribution. It's probably actually cheaper to distribute on CD then on
floppy these days anyway.
