Re: Perfect fidelity
The question surely is what is "good enough" fidelity?
Going way back to the late 1980's with all the work on MAP/TOP and GOSIP. Whilst the IT crowd got obsessed about the networking stack, it was obvious the real challenge was the application standards, which were rapidly evolving at the time.
The keys to fidelity were Standards and (interop) testing and governments using their buying power to put teeth into the Standards. Unfortunately both the UK and US governments back tracked on GOSIP with the end result of getting themselves largely locked into Microsoft Office for 30+ years...
