I haven't played with this too much, but does Mist need a local copy of the entire blockchain? If so, I'm not sure these decentralized applications will be accessible to the average user. On the other hand, the application in the tutorial directly deals with Ether so the user may already have a fully validating node. Are decentralized apps created on Ethereum intended to always involve Ether? I suppose Ether is used to reward the miners for hosting the application?
