The lack of fungibility is one more example of the attempt to make this product a failure. Traders will have two choices--either keep close track of which exchange each trade was on or only trade one exchange. I would guess most will opt for the latter.
If nothing else, SSF's and Supermontage should be good for the sellers of PC's and monitors, as we are going to need more screen space to keep track of everything. Or else just trade the mini's on globex and forget the rest.
