Did I really say Part 95?  And of all the CFR sections, it was 95?  Sheesh 
and I can't use lack of coffee as an excuse!  Specifially, I meant Sec. 
15.103(d) for starters...

Except that the FCC and the federal courts still have exclusive jurisdiction 
over all EM matters in the U.S.  In addition to the League, organizations 
like the NAB and SBE (to protect AMBC listenership) have been engaged in 
these discussions.  I've not kept up on any related FCC petitions, but I'm 
not aware of any Petitions for Rulemaking (PRM) that affect 15.103.  If 
there is/are, I would like a cite. The FCC can invoke a PRM on their own 
motion -- but it will never happen.  That's why it will take you, me, and a 
damn financially strong lobbying effort to get any traction.  This is 
probbaly a more important issue to us than spectrum protection -- or at 
least equally so.

I could see existing devices being grandfathered in.  There's just no way of 
going back an enforcing a rule change on existing appliances.  But there's 
no reason why EMC compliance cannot be invoked on new product to some of the 
same standards used in the EU.  I'm not an expert in EU EMC compliance, but 
I'm lead to believe there's no such 15.103(d) type of exemption there.
