Solution 1: (Requires lots of work)
1. Export PPT to XPS
2. Write a custom display (UserControl) which will display your XPS. (Refer to http://www.wictorwilen.se/Post/Dissecting-XPS-part-1--The-basics.aspx and the entire 8 Part series)
3. Enhance your User Control (Developed in Step #2) to allow editing by maipulating the XPS' XML

Solution 2:
Integrate your PPT with SharePoint Office Web Apps 2010.
1. Open your PPT in an iFrame (using SharePoint's Url). Office Web Apps 2010 allows you to edit PowerPoint slides in a browser.
