In OO you are _always_ composing stuff from at least two sets of data and functions: the data and functions of parent, and the data and functions of the new child you are creating. In Plan 9, the standard / net might represent the parent, and /my/net that you bind on top of it represents the new data and new functions you create, in purpose of modifying the parent. Don't you agree that the semantics are roughly the same as in classical OO, even though the syntax, type checking and run-time vs. compile-time trade offs are different? Benefits in Plan 9 approach are numerous: language independence, free serialization, optional persistence, networking, object naming and object permissions provided automatically by the system, not by programmers.
