I have uploaded T10/08-469r4, the next revision of the iADT proposal, for discussion at next Wednesday's ADI working group teleconference.  A meeting announcement will be forthcoming later today

http://www.t10.org/ftp/t10/document.07/07-469r4.pdf

In this version, I've inserted an "interconnect layer" between the physical layer and ADT link layer.  This appears to work while avoiding changes to the link, transport, and SCSI application layer.  An "ADT port" is now an abstraction that connects with one other ADT port via an ADT serial, ADT TCP, or ADT UDP interconnect port.  At its upper edge, the interconnect layer provides a standard set of protocol services to the ADT port to allow it to connect with another ADT port, send and receive, and disconnect.  Operation of each service is defined for each of the three interconnect layer alternative.  At its lower edge, the interconnect layer uses hardware connections defined by either the ADT serial bus or the (newly-defined) ADT Ethernet bus.

The ADT Ethernet bus proposes electrical characteristics for optional LED output connections.

Cheers,

Paul
