Could we separate the open hardware discussion and the fieldbus protocol argument?? The open hardware discussion is about plug in boards, not remote IO.
I am coming to agree with Curt on the general idea of the IO bus. 74HC chips are good. )
It is my opinion that fieldbus IO packet should be in the number of bytes that I can count on one hand. I don' think you can pass around XML data and have short packets, and thus any real speed (tens of microseconds, preferably).
