Has anyone written an STS wrapper to Facebook Connect and Graph API?

Question

Has anyone written a secure token service that wraps the Facebook connect API that they are willing to share?

We are considering this as an alternative to using Azure ACS.

Sign into SharePoint 2010 with Facebook using a custom STS shows how to integrate the Facebook part with a custom STS. You can pretty much ignore the SP 2010 part (unless that's what you are using?).

Also, have a look at Startersts. Not specifically about Facebook but it does have a sample on how to build a bridge between OpenId and WS-Federation.
