Modify the IPv4-only browsers?  Sure.  But considering the continued
use of IE6 in China (per recently-published statistics from Microsoft),
sharing content there would be a problem.  Yes, it happens -- I shared
links just last year when I was organizing travel over there.

Making existing users change to deal with new technology -- which they
are not deploying -- does not seem like it would be successful.  
"Teaching old dogs new tricks" comes to mind.
