wing_walker, what you've suggested - a discussion of the possibilities of Spooz constructing its own derivatives trading exchange - is a tall request for most of us : ).
From a business philosophy stand point it makes total sense. In two of the business ventures (we know about : ) revenues will be reoccurring - that is, revenues and profits will be coming into the Company at constant continuing intervals. If Spooz chooses to build a niche trading exchange it would also have reoccurring revenues.
Reoccurring revenues is one important hallmark of successful companies. milo3
