It would be nice to see something about federated security using something like SAML - if you are a large enterprise and you have multiple SaaS providers you really want external services to be using your own internal directory (which is likely to be MS Active Directory) for authentication.
Actually, it would be pretty nice if someone could offer this as a easy to use service for people building enterprise oriented SaaS apps. Is anyone already doing this?
As far as I know, Nordic Edge (http://nordicedge.com/) provides solutions to quite easily make your SaaS app SAML enabled to login via a remote AD/IDP, but all their products are proprietary.
