much better than that you can invite them to write what they have done after Amiga. I know for sure RJ Mical did quite a lot of intersting stuff and has worked even on the Playstation3. Someone is working at Microsoft, and someone like Sassenrath has created a internet platform/interpreted language.
For me the best engineers have done much even beyond the Amiga...
Also check out for V.Andrade and other guys at Commodore not Amiga related (Yannes for example)
