Yep. You should be able to just copy your Python installation + python22.dll +
maybe your favourite editor to CD. That's also how I distribute python apps
myself.

Yes, but that's no problem at runtime.

If you want to make things reasonably independent of the Linux system at hand,
I'd recommend to link statically wherever possible. That will require patching
the Python build process, however.

Another approach for Linux is to copy all the shared library dependencies in a
special directory, say /linux/lib on the CD-ROM and make a start script that
sets LD_LIBRARY_PATH to this lib directory, then executes python, IDLE,
whatever.
