As an aside, since it's getting on time for me to move on from my current employer, are there any companies doing these kinds of hardcore engineering projects any more outside of the defense industry? I have spent most of my life (until recently) doing systems work (sometimes but not always big-iron embedded) and I kind of wish companies were still investing in ~30 person teams for big engineering projects. I've always wanted to work on a Windows NT ... but no more routers.
