The text above is not mine.  The text below is mine.  It is  
unfortunate that
they appear to have both been attributed to me.

Agreed.  However, I don't think it's too late.  I think it is worth  
the effort to start
talking, especially to the enterprise world about dual-stacking rather  
migrating/converting/transitioning to IPv6.

A small change in words may garner a big change in sentiment.

At this point,  I think it is worth a try.
