Agree. And just to qualify "yet", getting widespread support for DHCPv6-PD 
on 3GPP networks is probably 1-2 years out. It's in the standard 
specification (3GPP release 10) already, but getting stable code that does 
this is probably 2013 timeframe or later. Then we have the whole mess of 
getting cellular devices to actually support this as well, and judging 
from current device support for IPv6, I wouldn't hold my breath. I do 
encourage everybody to request support for this from device vendors if you 
ever procure this type of equipment!

For those so inclined, 3GPP UMTS release 10 specifications can be read at 
<http://www.etsi.org/deliver/etsi_ts/123000_123099/123060/10.09.00_60/ts_123060v100900p.pdf> 
(section 9.2.1.2), or if you want to read the LTE specs, it's at 
<http://www.etsi.org/deliver/etsi_ts/123400_123499/123401/10.08.00_60/ts_123401v100800p.pdf> 
in section 5.3.1.2.6.
