Protection of revlet

When a revlet is created and linked to in an HTML web page, what prevents a user from downloading the revlet? How does one protect their revlets from free distribution?
Thank you.

Dear Scott,
The protection of the revLet is not in being unable to download and redistrivute it, but in the special encryption and the inability to change it. Display your name and URL in the revLet, for a start. It should also be possible to validate the revLet when it starts up.
Best,
Mark

How would you validate?

A very simple way would be to "callback" to a cgi-script on your own site: given that revlets by default can only contact the site from which they were downloaded, this should fail if the user downloaded it to his desktop or uploaded it to a different server of his own.
