Liquidity Derivatives - the next OTC?

Given the drive the FSA is making in forcing financial institutions to implement "Liquidity Risk Management" (see background on JWG-IT site) are we going to see renewed interest in the creation of "Liquidity Derivatives" to hedge liquidity risk? I found the following post on the subject applied to hedge funds but not much information else where, although Tony Jackson did an interesting article on liquidity in the FT last week, indicating that liquidity derivatives have been tried before with little success.

I was thinking of the advent of credit derivatives being driven in no small part by Basel II regulation on capital charges for credit risk. Maybe given the current battle going on around OTC regulation (see FT feature today) there are institutions working on liquidity derivatives but nobody in the finance industry wants to admit that they are already creating the next "innovative" OTC to nullify regulatory charges?

Mr Geithner better watch out, innovation will always beat "rules" in my view...
