In our case we're an FPGA shop looking to transition. There really needs to be a support group for people like us. We have a hard time figuring out what's even feasible.
The difference these days is that with the death of Dennard scaling and Moore's law there's a place now for customized hardware. You really can beat Intel and even NVidia now for specialized workloads with FPGAs. Of course you'd be even better with an ASIC which is why we're leaning that way.
