Does the DMX capability provide a full universe of addressable space?
Personally I think the audio capture would be useful, but I am biased
there :)

DMX just looks like serial data to the FPGA. Nobody has actually written MIDI / DMX interfacing code yet but there is no reason it couldn't do full universe of addressable space, pretend to be multiple separate different devices or anything else in between.

We currently have 3, one for each room and a spare as far as I am aware.

You should definitely get a few more of these. We have found that the cables eventually fail after being rough handled by too many presenters.

This is great news! I would love to replace the BlackMagic cards with
opsis boards

There will also be the option of using the Opsis as a HDMI to SDI converter if you really want to use SDI as your long runs.
