There are existing technologies, such as Javaspaces which do this kind of thing 
really well.  Javaspaces has commercial as well as open source implementations. 
  You can look at the River apache podling, the blitz Javaspace by Dan Creswell 
and products such as gigaspaces.  Javaspaces is a very predominate player in the 
financial services market were time to "action" can cost you billions.
