I don't understand. Are you talking about adding functionality similar to
Future.get(long timeout) on top of an existing byte channel? I was talking
about the different between:

read(ByteBuffer dst, A attachment, CompletionHandler<Integer,? super A>
handler);

and

 void read(ByteBuffer dst, long timeout, TimeUnit unit, A attachment,
CompletionHandler<Integer, ? super A> handler);

As far as I know you can't implement the latter in terms of the former
because you need to pass the timeout values to the underlying OS. What did
you mean?
