Anybody know about 10 gbit switches? Makers?

OSUBeaver, 10gea.com might be quite helpful. So would Google...
Cisco, Extreme, Foundry, and Force10 are the folks I know in the 10G space. Force10 is a start-up, and unfortunately in these times you probably still want to steer clear of start-up vendors -- too much risk of them going away. Among the rest, as far as I know all three have oversubscribed 10G line cards for their high-end modular chassis switches; that is to say, the line card might be a 10G interface, but the backplane connection is 4-8Gb/s depending on vendor, so you'll never move 10Gb/s on a current chassis system. So you need to think of 10G as being a standards-compliant multi-gigabit interconnect, rather than being a full 10G today. Obviously, everyone's net-gen systems will be able to handle a full 10G line rate interface.
The 10G interfaces I've worked with so far all have some gotchas - they're first-gen all the way. But they really do work.
10G over copper is solidly in the research phase in the IEEE. From the studies that I have seen, cat5e you can forget about, cat6 is very iffy at any useful distance, and cat7 is approaching practicality. It will probably be a couple of years before 10G over copper is a touchable reality and longer still until it's product.

So you're saying that Cisco's new-ish Sup720 is pushing less than 10Gb/s on the backplane? The Cat 6500 has been able to push 256Gb/s (not cheaply, mind you) for several years now. Properly equiped, with the proper fabric cards, blah blah...
A quick scan of Foundry's high end switches are also claiming MUCH higher than 10Gb/s on the backplane. I can't imagine that they are claiming two orders of magnitude higher without something to back it up...
