Sorry! The only thing I can say in our defense is that this is pretty trivial compared to installing a lot of scientific computing packages. But seriously, we'd like a drag-and-drop Mac installer.

Then there's also the general appeal of doing big data work a la Google docs or Gmail. The trick is getting the user experience to be good enough on the web.
