+Instead of running guestfsd (the daemon) inside qemu, there should be
+an option to just run guestfsd directly.
+
+The architecture in this mode would look like:
+
+     +------------------+
+     | main program     |
+     |------------------|
+     | libguestfs       |

+Notes:
+
+(1) This only makes sense if we are running as root.
+
+(2) There is no console / kernel messages in this configuration, but
+we might consider capturing stderr from the daemon.
+
+(3) guestfs_config and guestfs_add_drive become no-ops.
+
+Obviously in this configuration, commands are run directly on the
+local machine's disks.  You could just run the commands themselves
+directly, but libguestfs provides a convenient API and language
+bindings.  Also deals with tricky stuff like parsing the output of the
+LVM commands.  Also we get to leverage other code such as
+virt-inspector.
+
+This is mainly useful from live CDs, ie. virt-p2v.
+
+Should we bother having the daemon at all and just link the guestfsd
+code directly into libguestfs?
