Assume an IAM role. An interesting way of doing IAM roles is to give the instance permissions to assume another role, but no actual permissions by default. I got this idea while setting up security monkey: http://securitymonkey.readthedocs.org/en/latest/quickstart1.html#setup-iam-roles.
#!/bin/bash
#
# Assume the given role, and print out a set of environment variables
# for use with aws cli.
#
# To use:
#
# $ eval $(./iam-assume-role.sh)

Nice little trick to have a deployable shim to a real python package
#!/bin/bash
#
# The package name and version are parsed from the filename (in this case
# PACKAGE=virtualenv V=1.11.6). The package is downloaded to /var/tmp if it
# isn't already there, and the main script is executed. This is sort of like
# having a lightweight shim to the real remote executable package. Very cool,
# I can't believe I didn't think of this sooner.
#
# This same file will work for (almost) any package.
