Matthew Dillon is planning to start userland VFS work in about a month; this led Andreas Hauser to ask if FUSE could be brought in as for FreeBSD. Csaba Henk, who ported it to FreeBSD, said “yes, but better“!
A running description of activity related to DragonFly BSD.
Why not rather go for 9P ? A protocol modelling a VFS – pionered by R. Pike and K. Thompson for Plan 9 from Bell Labs.
A linux port is at http://www.v9fs.org/
Atleast read up on it on the Plan 9 homepage, and the section 5 man pages there.
Sorry- it’s v9fs.sf.net not http://www.v9fs.org
