Geneva is the code name of Microsoft's identity framework (and it replaces Zermatt for those of you who have read about that). Geneva is actually three things:

• Geneva Framework.
• Geneva Server a security token service (STS), also the next version of ADFS.
• Windows CardSpace "Geneva", formely known as CardSpace 2.

The Geneva framework is all about making it easier to build claim-based applications and services. The framework also contains about 90% of the STS code for Geneva Server so it makes it radically easier to create a custom STS compared to the amount of work necessary today. Although I haven't had any time to play with it, I'm quite sure that it will (not all in the CTP) support all things I wanted when writing my post on WCF STS. The reason that I'm quite sure is that I had the possibility to speak with some of the team members during the last week, discussing some of the features.

The bits are available here.
