Does a CMS plugin for .net MVC project exist?

Question

as SO digested my title i found

If you're going to integrate a ASP.NET WebForms CMS with ASP.NET MVC 2, you're going to have to do your integration at the API level (assuming the CMS has an API).

That raises the question - do any of projects exist where an api mapping some of the housekeeping functions of a generic CMS can be leveraged by my own service?

thx
