I want to have an Excel Doc and a Word doc that I can collaborate on with multiple users over a LAN NOT cloud services. In other words I would, for example, want to have them reside on a network share and have 10 people open them up and actively change cell data in the workbook and have it reflated on all the other users systems immediately, ala Google Sheets (I know, that's in the cloud, but the way it works is what I want, but on a LAN). Same for the Word doc.
We currently update this data on SharePoint, but unless you refresh you never see the changes and the interface to SharePoint worksheets just plain sucks.
We are using Windows 7/Office 2013.
