Yes.

IOW: if you ever worked in the linux kernel or in the GNU utilities, you risk contaminating OpenSolaris in the case you decide to move; if you ever worked in OpenSolaris, you risk contaminating the GPL'd guys.

Draw your own conclusions.

Mutual incompatibility.

There are two kinds of contamination to consider. For the copyright kind to occur there would have to be copying of code from one system to the other. That should be easy to avoid. In the case of patent contamination, as I understand patent law (and IANAL), the history of the programmer only matters with respect to penalties that might apply. The question of whether or not there is "patent contamination" does not depend on what the programmer knows.

I agree. The danger of accidentally contaminating is mythical. You can't accidentally copy computer code -- at least not enough to create more than trivial damages to the copyright owner. Copying a technique or general structure isn't enough to violate copyright.

Some people worry that code that wasn't copied might nonetheless be proven to a court's satisfaction to be copied if it accidentally is identical to the original and the author had access to the original. But again, it would take quite a coincidence for more than a few dollars' worth of original code to look identical to other code.
