Here is an overview of the issue:
        Key: DIRSEDA-10
    Summary: UDP Imeplementation
       Type: Task

     Status: Open
   Priority: Major

    Project: Seda Framework

SEDA framework currently supports TCP/IP only.  Supporting UDP is the primary concern to make
it widely usable.  But because of its essential difference with UDP, we have to approach carefully.

Datagram channels does not have notion of connect/disconnect.  DatagramChannel.validOps()
does not include OP_ACCEPT, so UDPListenerManager and UDPInputManager should be incorporated,
and it is slightly different from current routing process of SEDA.  This difference must be
handled smoothly to resolve this issue.

Because there is no explicit connection/disconnection notification, the policy how we should
maintin and expire ClientKeys.  Simplistic implementation will have an timeout-based expiration
mechanism.  As an alternative, SEDA can give up managing the sessions of UDP events although
I'm not sure it is possible.

Any ideas?
