Yep, that was what I was referring to. I've seen many of those (and I think I even participated in one). My impression was that it wasn't something on the immediate radar. I started looking harder into it recently because I was given someone's library to integrate into something else I had. It's not the end of the world, but it is something I wish I knew more about so that I could put forth a better argument for. My view is definitely narrow, so I am sure I don't see enough of the whole picture. It might just be too difficult in practice.
