I'm helping Norwegian customers withdraw, at the same time reducing the number of withdrawal requests from MtGox, by automated buying of bitcoins for NOK at a rate 1% below best MtGox bid.
You really shouldn't so that, it will be taken advantage of by arbitragers. Yes, the money will be locked up for a short while, but they can probably earn 6-8% profit/round trip with minimal risk by buying coins on Bitstamp and selling to you. That's a lot of money to give away.
