> It may be worthwhile to enhance the various processor implementations to accept a Collection<IoBuffer> or IoBuffer[] and perform a gathering write across all the collection members.  For datagram protocols, this would allow messages to be composed without copying.  For stream protocols, this might simply improve performance.  In addition, stream protocols could benefit from doing gathering writes in general when there are many buffers queued up.
