This is related to an idea I had a while back: we should have a library of old Sage versions -- together with a collection of virtual machine images that will run them. Sage 2.0 was January 2007, so if you wanted that, you'd download a binary together with, say, an image of Ubuntu 6.06 that will run it. Then the problem is turned into the problem of getting the VM to run. My impression is that the file format for VM images is pretty stable, so this would be a good way to archive old versions for (relatively) easy access. And no, sorry, I'm not volunteering to do this. :) Dan -- --- Dan Drake ----- www.math.wisc.edu/~ddrake/ -------
