Why not? To ask doesn't cost a thing (but my own nerves).
And for me they could be willing to make an exception :-)

But you also want to keep control. Ain't that a contradiction?

Depends on the chocolate - I vote for cool Toblerone ;-)
How much do you earn a year? Whether this is enough only
depends on your usual way to spend the money...
I just proposed to setup an environment where industry could
relate to and go for contracts and license. Because either one
wants to stay in control of something, then one has to take the
responsibility, or one doesn't and is free of it. Even LEON is
maintained by a company - Gaisler Research.

No, in my opinion the cpu is not the center of the hardware
because if you have multi cpu on chip which one should be
the center? I see a cpu just as an information modification
Look at Richard, he thinks the display is the center of all.
He is misleaded too. He just sees it from his application.
The center may be the communication but from where to where?
Look at cpu vs. memory. There is communication taking place
(address vs. data). Look at two cpus - the same.
Me think the center is the exchange of information!

No, why make a flame war. But it's very interesting to read
your opinions and fears.
