Due to certain limitations, particularly with Mac OS X and multicast data (sACN)  please consider the option to have ranges of universes. This would be really useful to keep the overall IGMP subscriptions down.

Specific use case: my main rig is universe 1 - 40 and then we have things on universe 81 - 84 and 221 - 222 (I don't have any control over this) we could set 3 ranges A: 1 through 40, B: 81 thru 84 and C: 221 + 222 totalling 46 universes, not all 222.

You could also use this option to shift which universes capture responds to in a festival pre-vis situation where different consoles are given different ranges of universes.

Please let me know your thoughts on this.
