In response to both Jericho and Bees;

I wasn't actually proposing a market place for 0days. My point was 
something like; index futures on products that is built on a model where 
0day is a part of the equation (perhaps think of it as vega).

for example, Exchange 2003 could be tied to an index and each index point 
could be assigned a dollar value. Theoretical value will than be 
calculated by a model and the rest will be left to the market forces to 
settle the premium. Hedgers can than take long or short positions 
(depending on how the model is formed) to offset their IT costs and 
possible damages from intrusions and other liabilities. Speculators can 
also take on counter or similar positions depending on their outlook.

Yes, there is an obvious flaw which is the risk-free arbitrage by anybody 
who holds a 0day against Exchange 2003. But I believe this could be 
acceptable as part of the market at its infancy and since all or most 
arbitrage possibilities gets discounted by markets eventually, this model 
will lead to less outstanding 0day in underground/criminal circles, 
perhaps even more secure software eventually ?


SDL versus the free market ? Which is more efficient ?
