[nznog] Recordings of 2015, and license

I almost hesitate to bring it up again, last time there appeared to be no consensus about it, but... Do we know what, if any, license the recordings of this years NZNOG are? In theory, it should have been stipulated in the contract with the recording/streaming company, along with the speakers agreements. Cheers, Nick -- Nick 'Zaf' Clifford
