Q had used MOS for Mo_sad in a post a while back. It's reasonable to think he meant Mo_sad in the drop today. I was the first anon to suggest the Media Object Server. Still think it was a good dig and am not ruling it out. But since Q used it before I am going to go with that first meaning unless it is officially cleared up.
And damn, this place can turn into a shitshow fast if you say something someone doesn't want to hear. Feel like I am talking to the extreme Left sometimes.
