Use ssh key's in connection to 3PAR instead of password - supported?

Does the 3PAR driver support ssh keys instead of passwords? As mentioned by someone from Red Hat: Looking at the driver code[1], as recent as on the Pike release, the san_password is actually a required parameter. Which makes an ssh key pointless.
A password is required for the REST API anyway, so one can doubt the usefulness of using ssh keys.
Who can I contact about the 3PAR python driver for more 3PAR related questions?
