I have an integration dashboard I've written that currently works with On-Prem SharePoint.

Basically, you give it the address of a SharePoint server, and it passes in your NTLM credentials obtained through forms auth, and can access lists and libraries for you.

Can I do the same thing with O365? I can see how the App model works with CSOM, but this cannot be an App for a few reasons.

I assume there is an object model used by Windows Apps for SharePoint integration, but I can't seem to find it at the moment.

You can use Microsoft.SharePoint.Client.dll .NET CSOM not only in SharePoint APPS, but also in other client solutions based on .NET. There are also more-specific .NET CSOM implementations for Silverlight and Windows Phone.
