This means that folding at home could engineer a web browser client. This client can be in Windows, Mac OS X, Linux and with WebGL it can create a GUI since the worker won;t be in the way to prevent WebGL from working.
What does this mean in the future. TVs with the upcoming HTML 5 would have also browser with quite powerful GPU cards especially when the die goes down to 32nm or even less. Imagine a family running a web based client of Folding@Home while they watch a movie. Imagine how many millions of clusters can produce results.
Lets look at the future a bit and see the web based possibilities for just a few secs and if we disagree then its our right to erase it from our memories.
