I'm somewhat skeptical whether adding such an DOM property will
actually solve the problem.  I would expect that many sites that use
hidden plug-ins won't update to use the new DOM property, which means
you'll need a solution that doesn't involve the web site changing its
code.  One approach is to provide a UI affordance for playing the
plug-in outside of the web page itself.
