I think that that's the answer, put the whole OS and db on a
bootable cd or DVD. In 20 years they'll surely be no
problem running the whole thing from RAM so media access
speed should not be an issue.
The only thing to worry about is if the underlying architecture
goes away entirely. I suppose if you choose something common
they'll be an emulator.
