I was recently looking into this (top-of-rack VPLS PE box). Doesn't seem to be any obvious options, though the new Juniper MX80 sounds like it can do this. It's 2 RU, and looks like it can take a DPC card or comes in a fixed 48-port GigE variety.
The MX-series are pretty nice. That should be able to do VPLS PE, however I've never tried it - MX240 did it pretty well last time I tried. I've no clue how the cost of that switch compares to a cisco 4900 or something (not that a 4900 is anything special - L3 is all in software).
Are there any applications that absolutely *have* to sit on the same LAN/broadcast domain and can't be configured to use unicast or multicast IP?
The biggest hurdle we hit when trying to do TOR L3 (Cisco 4948s w/ /24s routed to each one) was devices that either required multiple physical Ethernet connections that we typically use LACP with, or any environments that do IP takeover for redundancy. Both are obviously easily worked around if you run an IGP on your servers, but that was just insanely complex for our environment. It's hard to convince people that a HP-UX box needs to work like a router now. So now we have a datacenter full of 4948s doing pure L2 and spanning tree... What a waste :-)
