| I'm yet to read the article but regarding this, Dante is a
| massive step forward and is currently dominating the market but

| like AES67 disrupting the market that MADI currently hold than
| Dante. It does naturally help Dante's case that it has an AES67
| compatible mode.

| isn't needed for this use case yet.
