I'm evaluating the options for a CMS in ASP.NET MVC. I'm currently working on a multi-tenant app that requires CMS funtionality. I've been looking at N2, Mojoportal etc, but I'm also interested in what SharePoint Services could bring to the table. Specifically I don't want a SharePoint site but rather I'd like to potentially use the sharepoint object model, db tables, etc. to form the core of the CMS.
Is this possible with SharePoint or am I going down the wrong path? I've not had much experience with it.
