Py2exe manages to load .pyd files and dlls from zip. Apparently they have written an alternate dll loader that does not need the file to be on the file system. This is used for single file apps.

I don't know if it is possible to write a portable Unix equivalent for .so files.

If you mean, portable to all dialects of Unix and Unix-like systems, I am pretty confident in answering "no". But it might be possible to support many such systems, e.g. by exploiting the DMG format ("disk image" within a single file), native to MacOSX, that can be used in Linux (and I believe in some other Unix variants) by mounting the file as a "loop device" (there's all sort of niggling issues, such as the need to be root to do so, but perhaps there might be workarounds...).
