I work in the research arm of a certain extremely famous hospital in a small town in the midwest, and once you guys get your histo package up and running, I'll definitely check it out. It's a crowded space, but we're always on the lookout for the next big thing.

I do wonder, though, about the wisdom of doing that sort of analysis in the cloud. Our projects routinely use several terabytes of images (we have about 150TB stored right now, most of which is full-slide images), and uploading them somewhere isn't just a simple fire-and-forget procedure. Cool analysis algorithms might not be enough to make up for the headache of having to wait for days on end for the uploads to reach the cloud.
