they are now, yes.  But until the sup2t started becoming available a couple
of weeks ago the only option for the 6500 was a sup720.  You're right that
this was only pushed on the enterprise market.

Of course, if you wanted a 10g capable service provider router and didn't
want an asr9k, they were pushing the 7600 because the 6500 is a switch and
the 7600 is a router and the two are totally different, no really you've
gotta believe it.  But at least the rsp720 could handle ipv6 fragments better.
