How exactly does this work, if they don't have access to the original? > 8. Our service may automatically delete a piece of data you upload or give someone else access to where it determines that that data is an exact duplicate of original data already on our service. In that case, you will access that original data.

I don't think it does. I think that is just there for legal reasons.

They take a hash of every X MB of your data before upload. If the hash already exists, then they don't upload it. You just get added to the access list for that particular chunk along with the others who have uploaded it.

  Seems unlikely that there would be many collisions though...

  That can't be the whole story. If Megaupload gives you access to the ciphertext encrypted with a key that neither you nor Megaupload has access to, that is useless.
