re: X32 Discussion
AES50 will only work as a direct cable connection with no routers or switches.
The remote control idea is quite interesting, but you would then use the LAN connection (and that could easily be wireless), not the AES50 (same plug and lead, different signals)
Haven't seen any mention of using one x32 to remote another, but if it is perceived as a good idea, they'll probably implement it. The advantage of doing that is obvious, but will limit how much monitor duty you can put on the onstage board, and you will not have any available audio at FOH, no input, no output.
Using the AES50 interface, all audio will travel back and forth and thus be more vulnerable to cable breach, but you'll have audio in out available at FOH, have more processing power etc.
Edit: some of this post is rather redundant after the last posting by Mr, Cagle, but I'll let it stand.
One thing though, SAC have lots of layers, so several remotes can work without disturbing each other, I think it would be harder to work a dual X32 remote arrangement without the two operators getting in each other's way.
