Web server. FTP server. Network file server. cp. mv. cat. dd.
In short, vfs->net (what sendfile already does) and vfs->vfs are probably

Classical bulk data copy applications.
All the other stuff I can think of really does want to look at the data,
and we can already handle virtual memory just fine with read/write/mmap.
