downloading revlets to local computer

[Kurt Kaufman]

In Firefox, as I imagine to be the case with other browsers, a web  
page can be saved with all of its supporting files: images, audio,  
video, revlets, etc.
If a revlet is downloaded in such a manner, and it requires access to  
data not included on the web page (but referenced by the revlet), this  
would leave the downloaded copy of the revlet without [critical]  
resources.  Is this an issue to be considered?  If so, would a  
advisory to the user warn of missing resources? Would the check occur  
as the revlet was first loading?

Thanks, KK
