Some recent work that Eve Maler is involved in includes work with (among others) my colleague Andreas Åkre Solberg on an Interoperable SAML 2.0 Web Browser SSO Deployment Profile , where the bare bones of interoperability are laid open for the world to see.
I have yet to meet Eve, but keep track of (some of) her work and knitting by reading her blog.
