%X In this paper we examine an extension to Hoare\[rs]s
   Communicating Sequential Processes model called
   higher\-order concurrency, proposed by Reppy. In this
   extension, communication algorithms (or events) are
   first\-class objects and can be created and manipulated
   dynamically. In addition, threads are automatically garbage
   collected and channels are first\-class, that is, they can
   be passed over other channels. We describe the design of a
   Java package that implements the main features of
   higher\-order concurrency, with similar ease\-of\-use to
   Reppy\[rs]s Concurrent ML system. Our implementation can be
   easily extended to use a distributed system, which is a
   major limitation with Concurrent ML. We also hope to bring
   the idea of higher\-order concurrency to a wider audience,
   since it is extremely powerful and flexible, but currently
   only well known to the programming\-languages community.
