You are not being at all clear in your assertion.  Could you define what 
you mean by "unregulated"?  And who mentioned banning plugins based on 
W3C tech?

Your impression is wrong, and smacks of FUD.  The original Adobe viewer 
went out of its way to allow scripting between DOMs, and inline SVG (as 
far as the current technology allowed for IE and Netscape/Mozilla, which 
subsequently changed its plugin scheme).  The viewer integrated most of 
DOM2/3, XLink, and CSS.  I believe that internal builds allowed HTML 
inside SVG's foreignObject, though I don't think that was ever a public 
release.  They also experimented with XPath integration.  What more 
integration could you reasonably ask for?

Even assuming that's true (you've made the claim, but provided no 
evidence), what's happened in the past informs but does not dictate what 
may happen in the future.  Has attention been paid to specifying how 
plugins might integrate with W3C tech, regarding audio and other 
multimedia?  Can you cite any instance where a plugin creator explicitly 
ignored something like an audio control?

You've clipped out the most important part of my email, that which calls 
for a serious analysis of potential future functionality.
