Those that do not understand FIX are doomed to reinvent it badly. I only got an appreciation for the protocol when I implemented a FIX server from scratch. Even the wierd text+field delimiter encoding is not bad (except for performance of course).
Session management, order entry and recovery in FIX is well designed and well documented (although it takes a few readings of the spec to put the pieces together). The biggest issue is the plethora of underdocumented extensions that have been bolted on to satisfy niche needs. If you are lucky you can ignore them most of the time.
Another big issue is a lot of exchanges treat FIX as more of a guideline than an hard spec and you have to workaround the lossage.
The best exchange binary protocols I have worked with (at least here in EU, borrow heavily from FIX.
