Thanks, this worked for some test programs, but then I ran into some
other problems when I had to import things (for some reason pig was
looking for python2.4 stuff even though I explicitly told it 2.7, I'm
assuming this is more of a CentOS/Jython issue).
I ended up using PyInstaller to package up my code and streammed though that.

In that case, rather than streaming through your python script P.py, instead stream through a shell script S.sh. The shell script can untar shipped or cached files, then run P.py. Maybe not completely elegant, but this approach works for me.
