Not sure if I understood the point above correctly, but there are 
several reasons that ISPs use not to deploy dual-stack...the biggest is 
simply fear of the unknown ;-)

Actually, in the past we (FCCN, the portuguese NREN) had several 
problems with Cisco routers, due to unstable "stable" IOS versions.  
But, after a bit of tackling, dual-stack is running indeed. Juniper 
routers were a great help to deploy dual-stack in an operacional 
environment. There were no problems at all.
