World Community Grid

No sooner than I get my office back from the rewiring folks, I get a note from a researcher at IBM asking for faculty who have proposals that might like use the World Community Grid for their work.
Just like many of the projects that Rheingold writes about in today's chapter, the WCG project uses idle computer cycles for grid computer work. The difference is that WCG is designed to be flexible rather than special purpose (it could do SETI or Folding or whatever). Their smallpox case study is particularly interesting -- good to read of a success.
Imagine that you had a complex problem that you wanted to solve using WCG, what would it be?
