Well we just picked up some Juniper MX80s here at work. That's right, they  
can route 80gbit/s and the OS that controls the hardware is basically  
FreeBSD at the core. (I understand the actual routing is fully done in  
hardware, but still -- I can get a familiar FreeBSD shell and do what I  
wish with these devices.)

I think FreeBSD is doing *just* fine.
