I've been in and can think of a few situations where it would be useful to have a CueSpider controlled from two desks - particularly in the world of broadcast. Perhaps mirroring a desk to another, or better yet, allowing a spider to be patched to multiple channels - I think either would be useful. My current scenario consists of a floor manager that moves between two locations during an event and needs control of the same cuespider. The workaround is to use two cuespiders in the same location, one patched to each of the two controllers.
