FPGA/CPU acceleration: Are companies using it?

Hi all,

There has been a lot of buzz about FPGAs to be used as accelerators for data centers (among others on Intel's acquisition of Altera). Which made me wonder: Are there any companies out there that have seriously adopted that methodology, except Microsoft's Catapult project? I'm not talking about companies offering solutions, and not academic research projects.

Really for the sake of curiosity, can anyone point at a big company that has FPGAs crunching data for them in a room full with hybrid processor/FPGA computers? Or even a not-so-big?

Thanks,
Andrew.
