Jason -do you mean any Java output stream type will work (as all Java IO stream types ultimately use bytes), and that the byte stream produced will have the bytes put in an accepted standard order by the writeTo method? In other words, using the writeTo method for *any* Java output stream type will produce a series of bytes that will *always* be able to be read using the C++ equivalent of parseFrom on the C++ side?
