I don't think there is a direct correlation between the raw ByteBuffer
or event you see from Netty to an InputStream/OutputStream, but you
could probably simulate the byte passing portion via the
PipedInputStream/PipedOutputStream and your own custom handler to deal
with the various events like Open/Close.  But if you are thinking the
performance from the context switch will be too high, its not clear what
you could do short of writing your own event consumption code and this
might mean the loss of using the library you chosen.

Best,
Johnny
