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).
