The whole high frequency trading, low latency mess is due to leave the
Linux world, at least for the hosts directly receiving the data, due
to the availability of FPGA's that can live on fiber optic
connections, physically adjacent to the stock market. I can say that
based on interviews I did some years back, without a signed NDA for
the interviews, and based on press articles on the technology.

Generating the rules for the FPGA's, now, *that* is an interesting
potential Linux market, and I can point people to job ads for
precisely this. Tying it back to Scientific Linux, I'd *love* to see
them using Scientific Linux for this due to the support available from
the Scientific Linux world for oddball scientific computing
requirements. And the Scientific Linux built-in integration for 3rd
party repositories like EPEL and ATrpms is invaluable.

Cool  thanks for looking into it!
