Bad form replying to my own post... while I'd still like to know if
this is possible to do with the tarfile class, it seems like using
subprocess.Popen() and calling tar from there with stdout set to PIPE
is probably the way to go.
I think this will result in the fastest way to copy files around.
Sounds like shutil.copytree() may not be all that robust (and probably
not very fast) in my version of Python (2.4.3 on RHEL5).
Still open to creative suggestions... :)
