Despite a lot of press indicating that the NMRA board actually approved an NMRAnet physical layer, the NMRA legal people and senior officers say they did not! The erroneously placed information is expected to be removed from the NMRA web site very shortly. In the meantime it has been confirmed that the NMRA Board has in fact issued an invitation for the working group to present to them in Sacramento in July.
I understand that a lot of email and phone contact has been had between the working group and the NMRA to clear up a number of issues. That is now possibly in hand and we can proceed in a more orderly fashion, we hope.
