http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License#Differences_from_the_GPL

Money Quote:
The main difference between the GPL and the LGPL is that the latter
allows the work to be linked with (in the case of a library, 'used by')
a non-(L)GPLed program, regardless of whether it is free software or
proprietary software.[1]

Basically: You may use the library for whatever you want, but you have
to release all modifications made to libzmq under LGPL.

  As usual, I'm not a lawyer. :)
