I need a method (preferably a plug-in or other transparent method) that will allow me to convert powerpoint slides to a windowed (preferably) display that could not be copied, or at least cannot be downloaded. It will be used in a class, so it's important that the content cannot be reasonably removed.
I would prefer a method that is automatic and transparent to me, but please feel free to share any ideas. Best would be the ability to upload powerpoint files and have it automatically modified, but I will entertain other ideas, as long as you can make it clear to me, how it will be used.
Would prefer the ability to allow the viewer to make certain on-page selections, if possible. Not a big deal if not, but please let me know.
