named_pipe_object is an odd name. Why "object"?

Construction with char const * attaches to an existing pipe, while with a std::string it creates a pipe? That's horrible. Those ctors should have the same behavior. Use an enumerated type argument to distinguish on behavior from the other or use the Named Constructor Idiom.

"some" in read_some() and write_some() is not helpful.

How does read_some() know the size of the supplied buffer? You need a size argument (or buffer type discussed separately).

write_some() also needs a size argument; you must account for binary data.

I don't think named_pipe_server is needed. One creates or connects to a named pipe. A single class can handle both aspects, through different constructors.
