for specific production needs that's a good point.  There are a lot
of other environments more universal that have greater potential
input from the community so will succeed as open code.

An example is the recent release of SELinux by the US National
Security Agency as open source, guidance on this continuing
project still to be provided by the NSA Information Assurace
Research Office.  It is an extension to Linux that has now been
incorporated as a module in the kernel (Linux Security Module).
NSA and the open source community are working to use Mandatory
Access Control which effectively places security controls around
every process and user on the system.

Before the internet became commercialized and almost universal,
there was no specific concept labeled 'open source' because
almost all prgramming available via ftp on the net included
source, which was by definition open.  Binaries were available
but were just prebuilt programs for people who didn't have access
to a compiler or else weren't able to revise the code or
makefiles for their particular platform.  When the more
commercial entities realized the power of the internet you began
to see programs made available that didn't include the source.
There are and were different levels of commercialization, for
exmaple Sun provided binaries via ftp but kept its own source
closed, though their operating systems always included a generous
number of programs that were open and thus able to be revised or
upgraded via contributors with a shared purpose.
