Hi,

Back in 2005, the US Office of Management and Budget (OMB) issued a 
mandate calling on all Federal Agencies to have an operational IPv6 
backbone network by June, 2008.  As the date approaches, USG customers are 
increasingly asking whether individual products/applications are "IPv6 
compliant".

The DoD has also indicated that it is developing an Approved Products List 
(APL) on which certified IPv6 compliant products will be listed.  The 
intention is that any product purchased by the DoD must first be certified 
and added to the list.

We have some nongovernment customers (names cannot be disclosed) 
requesting for IPv6 support in NFS, and few of them are willing to 
participate in pilot program.  In addition to the customers, we have some 
requests from different product owners for this support, so that their 
products can be made "IPv6 complaint".
