Hi all,
I've taken Greg Stein's "small" distribution and (with his advice(*)
and help) created a mechanism for building compressed single-file
importable python libraries. This is cross-platform, depending only
on zlib (and Greg's imputil.py). There are a number of ways you can
create these archives - grabbing directories, packages or computing
the dependencies of a particular script.
Then, for Win32 users, I've taken it a few steps further. I've mixed
this with Christian Tismer's sqfreeze (based on /F's squeeze) and
freeze and created a compiler-less Python installer. You can also use
it much like freeze, except you don't need a compiler. The major
difference is that, once installed, it won't be a completely
standalone executable. The installer will unpack the dependencies
into the exe's directory. There will be no dependencies outside
that directory(**). You can pack in extension modules, dlls and
anything else you like. The python lib support will be contained in a
single archive file. So the equivalent of a frozen pure-python script
would be one self-installing exe that expands to 5 files - the
"squeezed" main script, python15.dll, zlib.dll, zlib.pyd and your
private support lib (something.pyz).

Oh yes, while the code has my copyright, it's released under a
do-what-you-want license. Mostly, I glued together what others had
done (freeze, sqfreeze, Greg's stuff...).

Mark's COM extensions (particularly, Python COM servers), you can't
get away with this.
