stream data

Hello,

i've 'derived' some of the stuff i wrote for a SocketFactory 
replacement, and i came to the following interfaces.

Any comments?

public interface StreamConnectionService
     extends Remote
{
     StreamData pollForInput() throws RemoteException ;

     void sendOutput(StreamData buf) throws RemoteException ;

     public void close() throws RemoteException ;
}

public final class StreamData
     implements Serializable
{
     private byte buffer[];

     public StreamData(byte[] buffer)
     {
         this.buffer = buffer;
     }

     public byte[] getBuffer()
     {
         return buffer;
     }


}

More importantly, a cheap "whisky"... :-)

Well, maybe. I've hacked-up a model of a TCP connection running over 
jini. The implementation is reversing the direction of the calls. It's 
basically polling for chuncks of streamdata. A single serverendpoint 
exposed on the internet serves acts as a rendezvouz for both the 
accept() and connect() calls. The device behind the firewall binds() to 
the rendezvous service, and waits for incoming connect() calls in a 
accept() call. The underlying endpoint family is servlet/httpclient 
based for easy deployment, but any endpoint family should be possible.

Maybe Mekon is a very good name for it.

The only river that flows in both directions is the Mekong River in
Cambodia. The river sits in such a low basin that when the tide rises
the river flows backwards. Sadly, Mekong is probably not a terribly
descriptive name for your construct...

I'm in desparate need of a good name for a bidirectional stream.

Stream, Channel or Socket are causing so much duplication, things like 
StreamInputStream etc.

hmm, a River?

And this one:

public interface ListeneningService
     extends Remote
{

     String getPublicId() throws RemoteException ;

     /**
      * Accept an incoming connection.
      */
     StreamConnectionService accept() throws RemoteException ;
}
