should i be able to add users to a cluster with the CreateUsers plugin?

Is it possible to add users to a currently-running cluster using
CreateUsers? My use case is that I have a cluster running for a class
that I'm teaching this semester, and each student has a login on that
cluster. I have a few users I'd like to add (recent additions who are
sitting in on the class), but I don't want to terminate the cluster
start a new one causing the existing users to lose their
configuration, etc. (in hindsight, I should have mounted an EBS volume
as scratch space, but I'll do that next time).

So far what I've tried is to create a new cluster plugin configuration:

[plugin createusers.bio599.fall2012.round2]
setup_class = starcluster.plugins.users.CreateUsers
download_keys = True
usernames = ss977, rr538, hhh34, mjg95

and run that as follows:

starcluster -c ~/.starcluster/config-nau rp
createusers.bio599.fall2012.round2 bio599.cluster

which fails with the following error message:

StarCluster - ( (v. 0.9999)

    home_folder = user.pw_dir

Thanks for any help!
