Interesting.  The tar format isn't adequate for this: the whole tar
file will be compressed at once, so you need to uncompress it all even
to import a single module.  The zip format is more adapted, but it
doesn't seem to have LZ4 in its registered codecs.

Zip can be used without compression as a simple container for files, though, and there's nothing that says those can't be .pyc.lz4 files.
