You could create a Bitcoin trade competition together with MTgox to get newcomers into Bitcoins.
Example.
To join, you need to buy bitcoins for say $100 to your bitcoin adress at say MTGox.
Send half a bitcoin to the competition adress.
Than you need to trade the ones you have.
Now the one who can trade these to the highest value will get $5000
The runner up will get $2000 and the thirdplace would be $1000 etc.
The winners also get to keep their Bitcoins.
The competition will only run once atleast 1000 persons have joined.
They must not have an account at MTgox previously.
This would mean that there will new people buying bitcoins for $100.000.
I think this can work.
The assumptions is that someone funds such competition with USD 10,000
No need of an exchange as a partner - independent competition will do - that way, people can use their preferred exchange, even OTC trading.
Also no need to pay .5 BTC to the competition - any smaller amount will do, used to (1) register a trading address with the competition and (2) build a small fund to pay for a script to be written.
Using the registration proceeds to pay a programmer to write block-chain explorer scripts that correlate the transactions times with the trading value - to determine the trading values and determine the winners - will leave more USD to be paid out as prize.
The rest as above - the prize levels are meaningful as they are and should attract many competitors.
The problems that could be anticipated:
Earn competitor's trust that the competition is real, prizes are real and the competitor organisers will not walk away with the registration proceeds - however small they are.
The period of competition - what if during the competition the market stagnates and there are not enough competitors to make it move? Automatic extension? How to determine that?
The original funder's intend - to drive the value to its highest level might not be achieved with this competition - sure, during the competition-trade the value will bounce up , but what will grantee that it will stay there after the competition?
