It was an interesting story (to me) of custom open-source software being used in media which was (tangentially) related to the topic we were discussing. Seems to fit into the workflow of manipulating and editing for broadcasting (including HD content during the olympics) as the Raven suite they developed tags audio and video making it available at the next step in the process of broadcasting.
Not an attempt to say "Ooooh, look everyone should start using this" because a) most people won't be running outside broadcasting suites; b) its horses for courses and I don't care what others use as it has no bearing on my choice.
You can actually use FFMPeg for editing video, but its exceptionally convoluted and done on the command line (far from optimal). Its also an exceptionally useful player in its own write, and allows you to avoid the codec hell that many people encounter (its sits behind VLC).
Does NLE mean Non-linear Editing in this context? If so there is more than lightworks, several of which are GPL'd and many that aren't, see the list
non-linear editing suites compared I previously linked if you're looking for choices.
