Turbocharging the web

What if you could share a computer-aided design (CAD) model and even allow a colleague to manipulate it from afar? "Click on this link, check out my design, and feel free to add more holes or fill some in," you might say. You wouldn’t have to instruct your distant coworker to install special software or worry about whether her operating system could run it. Imagine that all your programs and data were stored in the cloud and that even computationally intensive applications like multimedia editing ran just as well in your browser as they would if they had been installed locally.
