I'm not certain where to best ask this question. Please let me know if it would be better addressed elsewhere.
At the Apache Software Foundation we have an incubating project (named Toree[1]) that has a dependency on Zeromq.

What is the status and plans of your move to MPLv2? - Sam Ruby [1] https://wiki.apache.org/incubator/ToriiProposal [2] http://www.apache.org/legal/resolved.html [3] http://zeromq.org/area:licensing
