1. HATEOAS (RDF/Semantic web support for entities), 2. ASP-Net Indentity Authentication Integration (http://www.asp.net/identity/)
I've read somewhere where you don't see the need for hateoas support Demis, but I'd encourage you to revisit the subject... RDF semantic web is growing (ie RDFa), so at least support for applying sematic attributes to each object could be helpful (ie FOAF, Dublin Core, etc.)

Please provide sources where it's "growing", i.e. where are the live examples of services using it? Also please provide the real-world end-user benefits that this would enable?
Also it looks like ASP.NET Identity should be in a separate feature request.
