We are heading towards that type of deployment beginning next year with Juniper EX4200 switches in a redundant configuration. This will be pure Layer2 in nature on the switches and they will "uplink" to Juniper M10i's for layer3... the power savings, space savings etc over traditional Cisco 6500 chassis (plus all the cabling between cabinets which is in our case a nightmare) made this a pretty easy choice... and price too..;)
Somewhere on Juniper's website in the product info section they have deployment whitepapers on this kind of stuff if that's of interest.... Hope this helps..

Also, if you are doing layer 3 to top of rack do you guys have any links to published white papers on it?
