Aruba Networks Clear Pass Guest formerly Amigo Pod
We just got my hands on the latest release of Aruba Networks Clear Pass Guest, formerly Amigo Pod. So far so good, just getting the pre-configured .OVF imported and running on our ESXi server (tried getting it to work on Citrix Xen for about an hour and then gave up).
I am running this as a proof of concept internally, if you want to register for the demo contact me and I can get you the link. Below are the initial screen shots taken during the setup on ESXi 5.0.
