I think probably the best way to handle an ICO at the moment is to create a smart contract that takes investment from users in Ether. Have the smart contract locked in such as way as that the developers must put in a request in order to spend the investments .
The investors get to vote on whether the request should be accepted or rejected with the investors with the greatest number of tokens having the greatest impact on the vote.
Take for instance a request, "We want to spend $50 to get a new logo".
If a higher number of token holders vote to accept this than vote against it, then the developers can withdraw $50 worth of Ether to purchase a new logo. If they do not deliver then the investors are less likely to accept their next spending request unless an apology and explanation is given that satisfies them.
There could be a date by which the project should be finished and if the project has still not be finished and the investors are not happy with the outcome thus far then their ether can be returned to them by the smart contract.
This should be relatively simple to implement. Not sure what to call it. Maybe a DaoCo (Decentralized Autonomous Organisation Coin Offering).
