Is there anybody in Espressif with IEEE cred?

Hi guys,
I've been watching with intense interest about the new Ethernet standard called 802.3cg 10SPE. It is a MULTIDROP ETHERNET standard for short range, low speed embedded applications which are currently served by serial protocols over RS485 like ModBus, or CanBus.
As an embedded shop, we can't be more happy if there will be a technical solution for microcontroller to microcontroller wired networking over a bus, that will reduce the need to reinvent the bicycle every time for every microcontroller combination.
In the current draft, the maximum number of guaranteed supported nodes is only 8, despite of PHY still having A LOT of performance reserve left on both PCB and twisted pair.
The embedded industry people all want to push for more device nodes in multi-drop configuration, and better accommodation of embedded use cases. In July, the call for interest vote went well (http://grouper.ieee.org/groups/802/3/cf ... 3_0719.pdf), and the interest/adopter group is now being formed.
I believe this initiative is clearly beneficial to our industry at large as it

I believe this initiative is clearly beneficial to our industry at large as it
- greatly simplifies device designs that have to use multiple microcontrollers.
- opens door to networked multi-MCU designs even in very cheap and simple devices — this can also eventually become a nice commercial opportunity.
- it has potential to eventually change the wider embedded design paradigm to that of a network, instead of a "mess of point to point serial connections" or "one monster MCU to handle it all"
- the point above also implies a much higher value being given to proper embedded software ecosystem, finally forcing vendors to focus on portability and interoperability — things that never were strong sides of the industry.
