I've been thinking about this a bit too. I think you need to wait for maidsafe to have a released product.
Distributed storage means static websites without a backend. (Well not totally static, but they wouldn't save state outside cookies)
There is still quite a bit of value here for websites with questionable political content. (and hopefully not nauseating illegal porn)
So what platform would a distributed web-server run off ? Anyone seen any serious projects in this area ?
