It's pretty much Deferreds all the way:

Yeah, I'm all for flavouring backends with decorators.

That's why I keep trying to sneak this guy through ;)

You get chroot for free with the current FilePath based vfs
implementation.  In the previous version (trunk) of vfs there are
force user/force group and umask decorators.  I'd like to recreate
those once we get the new version merged.
