Some keypoints:

1. There is some non-GPL code in MySQL. But this software uses less
restrictive licences than GPL. Public Domain for example, so you should
not be worried about it. There is no reason to get "around" it.

2. Yes, MySQL has contracts with all needed parties. I also wrote some
code to MySQL and have signed contract.

3. Yes, it is interesting model in software world but actually it is not
so new model at all. For example if you get free ticket to cinema then you
don't expect receive free DVD too ? :). This is "dual licencing" and any
author of any inntelectual property is allowed to do so. GPL is privilege,
not limitation (for users) and does nut put handcuffs on authors hands.
