I have tried selecting every node on the camera, and still no curves show up in the graph editor. Could this have something to do with the renderability of the object? Or is it just a checkbox somewhere I missed?

Yes, I do know how to use a disk solver cache ... my issue is that my computer is not very fast, so I do most of my cloth animations at a fairly low base resolution. Once I get the animation right, I pump up the number of polygons in the mesh and render for real. This usually takes a while (hours) and I don't want to have to run the sim and come back to it to start the render. I really would like it to do it all in one process, so I can just start it and leave.

Thanks for the suggestions, though.
