With my "time traveller from the future" hat on:
- please commit this statement into at least one of the ZeroMQ git 
archives (eg, https://github.com/zeromq/libzmq)

- ZeroMQ was originally developed by FastMQ, which iMatix acquired 

- can you say something about whether that acquisition included transfer 
of all FastMQ copyrights to iMatix, and thus whether the FastMQ 
originated code/copyright is covered by this MPLv2 license grant; or 
whether FastMQ remained a separate subsidiary of iMatix and the 
copyrights remained separate[0]; and

- can you say something about your understanding of what proportion of 
the copyright FastMQ owned, at the time of the acquisition by iMatix 
(2009-11-01), versus what proportion of the copyright was owned 
individually by developers who might have been working for/with FastMQ.



[0] The press release says FastMQ became "a division of iMatix 
Corporation" which implies separate, but the copyright strings in the 
files got updated about 2 months later:
