This is really serious concern, and I think people just underestimate possible effect of a massive XRP "distribution" that is about to happen. In May, Ripple is coming out of beta, and OpenCoin will be giving away billions of XRP in wide-scale campaigns. They can easily run something like "every Facebook account can request 20K XRP for free!" which will be adding billions of XRP to the market in no time....
Where did you get this information? It wouldn't benefit the owners or silicon valley investors if they released XRPs so fast that they were devalued.
I expect this to be like an IPO where additional shares are released in an intelligent way to avoid devaluation.
