I don't want to have files repeatedly retrieved while I'm authoring and testing. When I run a title from a web page, if I close my browser the title file is deleted, causing my title to no longer run.
Titles run from the Internet are easy to disseminate.
You simply have the user select the course from a web page, or send them the Quest startup title via e-mail or floppy. Internet delivered titles also don't have to be installed on every user station or server. Quest will retrieve the asset files, used by the course, as needed. All files used in the course are then deleted as the course is exited. You want a controlled custom look.
