The feature you are referring to is IOS Server Load Balancing, it's
a limited subset of CSS features but fairly useful on the 6500 or a
fast 7200.
The Content Services Module (CSS blade) is very powerful and expensive,
but if you need to balance multiple gigabits of traffic is ideal.

If they did that, how would they sell the CSS hardware? :)
I would think that the closest you are going to get to that is the CSS blade
for the Cat 6500's. Although, wasn't there a version of code for the 6500's
that had some local director features in it awhile back? Or did you
actually need a local director blade?
