Actually, scratch that: the primary use case for things I've built in the past are lazily loading file systems, where you only want to fetch the file if it is opened for reading/writing. If you have to provide the backing file before it is opened, it would negate the benefits of using FUSE altogether. -- Han-Wen Nienhuys - hanwenn@xxxxxxxxx - http://www.xs4all.nl/~hanwen
