I used ByteStream because on my suggestion 'cause I though it would be possible to work with NIO and STreams (As there is a method to get a STream from a Channel on NIO). If this is not possible, we could change the approach to whatever other way. and if it's not possible to work with an sort of Buffer then we will have to stick with byte arrays.
