Hi again,
I think your characterization of plugins as something we impose on the VFS is unfair. Plugins exist entirely internally to reiser4 --- we
to be honest I hope the force from kernel developers will not take away any more abilities and features away from reiserfs! If reiser4 is tied witth VFS whats about ports to e.g. windows or other unix systems - its more or less a lock-in ... an own implementation could solve. XFS also does not integrate well into the linux kernel (its basically a big mess), so I don't think the "does not integrate nicely" argument counts at all. lg Clemens
