I do like the idea of this device.
I have something like 24 channels of mainly stereo outboard. I'm just sticking it all on one serial chain with Totalmix.
Totalmix is very versatile (it does m/s, so allows mono eq to be in the stereo chain), but at the extreme expense of user friendliness.
All it desperately needs is a front end like the flock software, which I am sure is possible to do with OSC and some programming knowledge. No one wants to do it though. I asked on the RME forum.
"NO! ZE TOTALMIX SOFTWARE HAZ ZE OPTIMAL DEZIGN!"
