Yes, I started reading it, too. As regards PCI, it seems sometimes too
wide and slightly off-topic, but it's also a basic and accurate source
of notions.

I was sure this material was intended to be real-time commented. In fact
some EuroBSDCon video streamings are available on Youtube, but in the
2012 case I could not find your tutorial.
Just in case a video already exists and has been published somewhere, and
only if you want to share it, let me know. But don't worry otherwise.

Got it. It's now too early to discuss about this, but if I manage to
write something, I'll keep this in mind and inform you.

Thank you so much, I'm glad to know this. No problem for any time-delay.

Ok! This is just a secondary issue now, but I mentioned it FTR.
Bye!
