JFFS2 surely doesn't scale very well. LogFS should.

I'm certainly interested, but didn't plan to go to OLS. Had I known about this three month ago... :) Linuxconf.eu would be the next alternative. I was thinking about doing a btrfs/logfs BOF there and your topic would fit in fairly well. Any chances you can attend?
