actually happening yet though.
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?

(Although for this specific application of the original poster, to support servers on different IP subnets requires the SLB function to NAT the client IP address as well as the server IP, to ensure return traffic flows back through the SLB. In this mode, it cannot use the PFC hardware switching.)
