Yes, it can go.

You definitely need the sources, that's where all the Python scripts
live. The C/C++ sources are stripped out already.
You can safe about 15MB like this:
  cd cci_apps_build/lib
  strip *.so
The biggest chunk in the source directory of the current release
(yours seems to be older) is the chemical_components library, with
about 87Mb. However, only a few individual files will typically go
over the network.

Yes, you are right. The naming is historical. If I get a chance I'll
change the name to x86_64 for future releases.
