RL: OK, so let's talk about the "infamous" RTLinux patent. What's up with
that patent?

...

RL: Could that potentially be used to block RTAI from being LGPL?

Yodaiken: RTLinux is released under the GPL. I have an agreement with
Linus that nobody who uses RTLinux with Linux will have to pay royalties.

My question: do you stand by this, at least? If so, will you put that in
writing for the rest of us? Did you really mean what you said, or did you
add conditions later, such as 'only unmodified RTLinux blessed by me'? If
not, then I should be able to backport most RTAI features to RTLinux and call
the result RTLinux. Would that be consistent with your agreement with Linus?
