I ended up doing a search for Rapport in EasyFind which will show one every-single-thing. There are 141 related files all over the computer...
In your home Library and in /Library and in /System/Library AND many files in invisible places so you really can't come anywhere close to completely removing it. Oh, you'll get rid of some by removing the app and extensions and the System Preferences Pref Pane but many more will be left behind.
There is no uninstaller that I can find and weeding out all those files manually goes into some "dangerous" areas.
I'm afraid a person is just stuck with all this junk all over the computer but if anyone has any ideas I'd be most greatful to hear them!
