I agree a standard protocol would be beneficial to everyone and is probably why those conferences are so useful. The problem is the barrier to entry is so low (for better or for worse) and the absolute amounts traded are so low (often fractions of a cent to the dollar) that the cost of implementing and following a protocol are probably high enough that its not worth it.
