Well, you figure we got quite a bit of firepower for one of the youngeer and smaller projects out there. Its a lot harder to get actual sites going with the CISS projected which they admit to. With internet distributed computing, Howard needs to do relatively little... setup a site, give out the client, record the results that are sent back. If people want to set up clusters and whole site, all the more power to the project and Howard involvement is only very minimal in that.
The CISS is definitely interesting and potentially worthwhile, but its much harder to schedule the time to commit the resources while internet distributed computing can run at any time and its not critical that all machines are running at the same time.
