Hmm, the blockchain approach seems cool, but if I'm not misunderstanding wouldn't this necessitate all users to have a copy of it in order to be truly decentralised? Considering the Bitcoin blockchain seems to be approaching 37 GB, it doesn't seem to scale very well to mobile devices. Though I suppose the proxy model used my SPV wallets would alleviate this somewhat at the cost of slightly increasing centralisation (i.e. there'd still be some service providers, just more & freer competition between them). Such a model seems to put a greater difficulty on verifying actions though, looking at the recent Bitcoin troubles where old versions of the Bitcoin client along with SPV wallets are affected.
You are right, as he said, not all clients have an equal share of the blockchain, just as it is in the bitcoin network as well. There are some bitcoin clients that download the whole blockchain but others rely on a block chain hosted somewhere else. This is a perfect combination i think. Not everyone has to download it but it can be downloaded so you don't have the single point of failure.
