    This is a good idea and welcome on the Teensy from my perspective.

    Not very much that I have seen. I have just set up the hardware to do some OSC-controlled synths with Teensy 4.1 at my ponderous weekend-project rate.

    UDP works across VLAN's
    Sometimes there are config. issues especially with broadcast packets.

    Another thought comes to mind: work on the protocol design and get this going on a regular computer with an audio interface first. This will give you an easy reference and benchmark baseline.

    It is very likely the CPU and ethernet hardware can do it. My reference is having done this sort of thing long ago on SGI machines and Mac's with slower processors than the Teensy. We were doing 8...

    It has the same DSP instruction support as M4. Main changes are wider bus (64-bit), faster memory, higher clock rate and big caches.
    It is more energy efficient which allows the higher clock rate.
