Not Not Realy

1. No Not At all when I worked on the X-29, cockpit integration, we were 
doing 50/60hz frame rates, and that my friend was along time ago.
2. Jets have been fly around by fly by wire for more than a few years, and 
have been using mil-1553 which runs at 1mb. or AIRINC-429. etc
3. The bus structure for the 777 etc. is AFDX Switched Ethernet. You just 
send / listen for UDP messages.
not a problem for 10baseT (thats 10x over 1553/429), you want faster 
100baseT, or Fiber.
4. and the advantage that you did not see is that you dont like a module? 
Take it out, replace it with software, or hardware.

maybe but most likely I'll have the first cut, up in a few months. (we 
write a lot of code in C/C++/FORTRAN/Perl/and a little Java), and it would 
just be the core modules, Pilot, FD, INS, NAV.
we are working on the message format right now, and message viewer..
