My biggest "problem" is that I think most of the people on either side of the fence have no idea how it would have to be played or the ramifications of it.
Because of the half-cycles, waivers, deadlines, etc, etc., you can only play 1 game of a series each half cycle. You can't play any games out of sequence. And, as you now know, you can only play if the other owner agrees to it.
I think the "LIVE, HELL YEAH!!!" people think they can sit down and play 7-15 games at a time. They can't if HBD is to remain true to form.
