Permissions packages that work with spark

Hey All, I'm building a spark app and am looking for a semi-rhobust permissions package that will integrate cleanly. I've found https://github.com/ZiNETHQ/spark-roles via google, and have used entrust / sentry in the past, but was wondering if anyone has any suggestions. The one issue with https://github.com/ZiNETHQ/spark-roles is the lack of a web based gui for adding teams / roles / etc.

Thanks in advance for any help.
