How to buy a million ripples? If someone wanted to buy up lots of ripples, say a million, how would they go about doing it?

Currently the exchanges don't seem to give good rates, and trading one-to-one with someone else would be inefficient. Is OpenCoin selling directly? At the current Bitstamp rate, it would cost $4444.44 to buy 1,000,000 XRP.
For now you can request a private sale at a good rate by emailing Bitstamp customer service or directly Nejc Kodrič  (nejc dot kodric at bitstamp.net)
