This is a good point you raise on the licensing of standards libraries.
I am going to also pass this along to the folks doing the general LSB
work. They too should be thinking about this as well as all groups so
we allow both commercial as well as non-commercial to build on what
the standards provide without worry of either losing IP rights or
having to deal with/provide software that works with proprietary libs.
Both sides need to be watched out for.
