Would it be possible to do the Following with these Scripts?
Forgers, Stakholders or some other trusted entitys post regulary what they think the current USD value of NXT is to the Blockchain.
The script Calculates somehow an average USD price.
The Script now uses its own funds to Buy and Sell an NXT Asset called USD at that price.
Which results in having an Asset USD that has a stable USD value without having a Counterparty Risks (at least as long as the Script has enough NXT to buy that USD Asset).
