Yes ... one of the points I was making is that it's easy enough to 
store the files in a protected way, but when you want to actually use 
them in Revolution you have to unprotect them.  Eg If you have a 50Mb 
QuickTime movie you'll need to write it out to a file on disk then set 
the filename of a player control to it.

Yes this is true, however I'm less concerned with this aspect as images 
will be degraded in quality.  I guess the point here is that all 
security measures you take have an impact on performance and usability 
in various ways.

I feel that supporting writing to image and movie objects in Revolution 
(and having the data so written securely cached for display) would 
provide a simple way of securing media delivery and avoid the issues 
with writing out to files.
