AFAIK that's entirely dependant on the filesystem and how it's created (and possibly the OS as well). So arbitrarily deciding each bit is 8 pages is a bad idea. I could see allowing for a setting that determins how many pages per bit, though, but I think we're also getting ahead of ourselves. -- Jim C.
