Perhaps I failed to convey my intent or you misunderstood it.  

What I meant was v6-only network + DSTM _without_ temporary address 
management.  IPv4 addresses would be handled over IPv6 tunnels by DHCPv4 
server, not the temporary address management system.   The only difference 
would be using existing protocol DHCPv4 for the task;  temporary address 
management would indeed also be possible, and perhaps even useful in the 
cases that addresses are used by a very small number of applications for 
short periods of time only.  But otherwise, it seems like a complication 
right now.

Indeed, I have read the latest spec (but only cursorily, the only major
thing that has changed is the applicability statement).  I also commented
on -07 (and DSTM-* technologies) on the ngtrans list (17 Mar 2002).  Have
you read my comments (I have received zero direct feedback)?
