Regarding Ed Berard's comments on software reuseability:
There are some aditional roadblocks in the way of reuseability. While
electronic engineers have been able to freely obtain integrated circuits
without anybody worrying about who has the "rights" to the design, the same
has not been true for software. The government tends to demand complete
rights not only to embedded operational software, but also to all tools
required to maintain it. This tends to prevent software designers from
reusing modules from sources who believe they have a vested interested in
their software design (as do chip makers in their chip designs.) This is
worsened because distribution of source reveals 100% of the design information
on a software module, whereas corresponding information (schematic, electrical
characteristics, etc) for an integrated circuit reveals virtually nothing
about the process technology required to make it. Certainly no company would
want to invest money in development of generic reuseable software modules if
it means the very first time they use a given module on a contract that module
is swept into the public domain.
