Agilefant RESTful web service interface under construction

Hey,

I'm implementing RESTful web service to Agilefant 2.
Simply the key concept is to implement REST -service by using Jersey (JAX-RS reference implementation) which produces Agilefant's payload entities in XML -response (by using JAXB).

I'm eager to hear any thoughts people may have about this kind of a feature.
Any technical support also received with pleasure.

And for the Agilefant team:
Do you have experience about certificate -based authentication in Spring Security?
Trying to find the right solution for authentication and posting username and password in HTTP-request ain't no wise way to go...
