At #librecast we've still got quite a bit of our work for @ngi Assure to finish merging in.
Speaking recently to a couple of folks we found that they didn't realise we make our code free.
We make it available as GPLv2 only or GPLv3 only. We love releasing our code to the commons.
We use #FreeSoftware as well. We couldn't do what we do without it.
@NGIZero also does insist that the code produced for it is released under an OSI approved licence.
