Jonathan,

Looks like it's working fine in boto. Next up, try launching the
development shell and see if the config parser is receiving the values
correctly:

$ starcluster shell
In [1]: cfg.aws
(press enter)

This will print out a dictionary showing the config values for [aws
info]. Make sure the "aws_access_key_id" and "aws_secret_access_key"
looks correct. They should look identical to your boto test in the
previous email.

Also, while still in the development shell, try this:

$ starcluster shell
In [2]: ec2.list_all_instances()

Let me know if the list_all_instances() command completes without error.

~Justin
