Yes, this is a good approach.  I have one question though:

Many real systems are not strictly tree-structured, because there are
hardware devices which connect via several different paths.  For
example, much hardware supported by OpenWRT comes with a built-in
bridge chip connected internally to a hidden ethernet card; a tape
library would have one interface for the robot and a bunch of SCSI
tapereaders; etc.

When an emulation of such a device starts up, it will want to bind to
several parents.  How will you represent this ?
