The Functional requirement is not discussed yet. There would be 2 code streams for the same requirement first for the app version of SharePoint 2013 and other would be webpart version of SharePoint 2010. Currently client only wants to focus on the web portion of SharePoint 2010 and SharePoint 2013 with an architecture that would be extendable to mobile version in future. SharePoint Authentication part would basically be covered in the .net portion. SharePoint would basically in a claim based authentication model.
