Was there actually no follow-up? Change of header?

I never got a chance to see it again. I ended up spending more energy with another Sun project that wanted to switch the CDDL license to the GPL, only because they wanted to avoid going through the legal approval procedure to ship mixed-licensed products. Maybe I'll share that story one day: it was another eye-opening experience.

Thanks! Also, you never heard back from the Dtrace expert? (silly question, ok)

Nope, never heard back again. I'm not too surprised, Sun was a big company.
