I first read about the Spam Cube , in the paper a few days ago , and was intrigued by what it offers. But at the same time I am skeptical, it seems to be promising a lot – and like many similar attempts before this have failed. There is a limitation of four computers , but then they mention you can use up to six , so not sure that the limitation is and why - though I can possibly speculate its probably how fast it can process stuff.

Has anyone else also seen this or heard of it and have any experiences to share?
