[security-dev] PicketLink SCIM Module

I've been reviewing the capabilities of the SCIM module (which are defined by the SCIM specification [1]) and someone correct me if I'm wrong, but it only seems to provide a subset of the features that we support in PicketLink. Specifically missing are authentication, and support for the extended relationship types (basically everything besides group membership). I'm wondering if it might be worth providing a PicketLink REST module instead, which would provide two sets of RESTful services; the first being a SCIM-compliant service, the second being a more proprietary service that exposes all of the capabilities of PicketLink. On top of this, I think it would be of huge benefit to provide both Java and JavaScript clients to consume both services. Anil has already implemented a Java-based SCIM client in the SCIM module, but imagine if we provided PicketLink JavaScript scripts that web application developers could drop into their app - this would be a huge development time saver. I'm also thinking that the JavaScript clients should support a variety of authentication mechanisms; BASIC, DIGEST, X509, user/password, OAuth, etc. This is kind of uncharted territory for me (REST-based auth) so any feedback or opinions on this would be appreciated.
