:::At least starting June I see no consensus having developed to mention Ayers at all.  That was the period of endless polling and article protection, followed by a stable period after that with less frequent attempts to introduce it.  It is hard to draw conclusions from February through May given the tendentiousness at the time and all the page protections and sockpuppets.  Before February the issue wasn't around.     
 *The proposal sounds interesting to find a neutral third party to resolve this issue once and for all, but I have a couple concerns and issues with that.  First, I am not sure there is a dispute to resolve.  The matter has been resolved and the decision is to not include Bill Ayers material to the article.  That a small vocal group repeatedly brings this up does not make it a real dispute.  If they continue to oppose a uniform consensus then dispute resolution becomes forum shopping.  Second, what process is there for article arbitration?  I see none listed at WP:DISPUTE.  Maybe I'm missing something but offhand I am not aware of arbitration being an option here.
