Hi,
 
I'm personally happy making it available under a different license.  However,
most of this work (and almost all the actual implementation) was by Keir
Fraser, so he'll need to OK it as well.
 
Keir, if its OK with you then can we replace the copy of lock-free-lib at
with one under a BSD-derived license?
 
Thanks,
 
Tim

Hi Tim,

Thank you (and colleagues) for your work.

I work on a large open-source project (OpenAFS) whose license is,
unfortunately, not GPL, and not viral.  It seems like an outside chance,
but we're experimenting with lock-free data structures in some
subsystems, and it would be interesting to us if there were a possiblity
of getting a product/project-specific license exemption allowing us to
use MCAS.  (It would be nice to be using a vetted, free library.)

Thanks for your consideration,

Matt
