I really like this project and I have been waiting for something like this to being done.

But I don't believe and don't like the presale model.

I would rather suggest forking the BitShares client, with or without supporting the AGS/PTS contract, the first case will bring a very good support from BitShares community.
A Distributed Proof of Stake can be used, so the blockchain could pay delegates (devs, marketing, etc) to work on the project, and some delegates reward could be directed towards the computing miners dynamically.
While the project develops, a system like the CureCoin used at beginning could be enough. Just register an user at folding@home, or parse the whole community stats at folding@home and/or other projects, and pay all of them or the ones that register in Zennet's web pool. That web pool will redirect the payments until we could integrate this into the client.


If you really want a distributed a decentralized model, the DPoS one is by far closer to that than a central presale.
