My whole point, if I may resume my conclusion to a few words, is that 
most Open Source folks don't care if you can't open your code for 
whatever reasons.  That won't encourage them to compromise on their 
fundamental principle.  It's up to those companies to balance the cost 
of maintaining their ad hoc proprietary stuff themselves vs the cost of 
opening up their code so it can be merged upstream.

Yes.  However, as I said, those compromises may not come on the 
technical aspects of the kernel interfaces.  Just like it is unlikely 
for companies to ever compromise on their profits.  Any compromise 
touching any of those fundamental aspects for their respective parties 
is bound to always fail.

In other words, let's save ourselves some energy and give up on the idea 
that a kernel shim only for a binary only user space library is going to 
ever be accepted in mainline.  This simply will never happen, period.
