Transition Planning for IPv6 as mandated by the US Govt

Hi, I was just reading http://www.whitehouse.gov/omb/egov/b-1-information.html#IPV6, released some time back in 2005, and it seems that the US Govt. had set the target date of 30th June 2008 for all federal govt agencies to move their network backbones to IPv6. This deadline is almost here. Are we any close for this transition? I have another related question: Do all ISPs atleast support tunneling the IPv6 pkts to some end point? For example, is there a way for an IPv6 enthusiast to send his IPv6 packet from his laptop to a remote IPv6 server in the current circumstances if his ISP does not actively support native IPv6? Cheers, Glen
