The development team consist of 1.5 developers (with myself counting as the 1/2, and the 1 developer is also responsible for production support escalations). We started by trying to modify the FAST 1.0 reference implementation, got about 2-3 weeks into it, then took about 4 weeks for a rewrite that replaces the reference implementation (mostly for performance reasons), all in C. Our firm is currently live with CME. Eurex we connect to as well. Basically we took the approach of writing separate "preprocessors", one for CME FAST dynamic templates, and one for EBS specifications, and generate the internal grammar files that the decoder can then work with, one extra step.
