I wonder if folks have had any new information on this yet?

Looking at the slideware, a few questions spring to mind:

- the performance improvement is only obtained when using new linecards, 
it seems with dCEF/aCEF -- otherwise it's back to 32(?) Mpps.

- it is not clear whether new interface modules will support both 
"dCEF720" and "aCEF720".

- it is not clear whether you can enable dCEF on a system which has other 
than dCEF720 or dCEF256 linecards (and performance tradeoffs of that)

- it is not clear whether you can enable aCEF on a system which has other 
than aCEF720 linecards (and perfomance tradeoffs of that)

- IPv6-enabled software for 7600 was slideware (not released for the
public) for about 9 months or more.  I wonder about support for sup720 and
the features.

- exact IPv6 performance was briefly mentioned only once ("up to 200 Mpps 
or so"), it would be nice to get better figures. 

- the price differences with previous linecards and new linecards (are 
they expensive or extravagantly expensive)
