OK, here's my initial try.  In one sentence, "the services manager is 
the module that coordinates the reception of service requests and 
their actual fulfillment by the web services (aka EDO's)."

In short, at a very high/abstract level, I see the SM doing the 
following:

* listening for EDO service requests
* checking to see if the requested service is "enabled" 
  (allowed to be run) on that node
* If it's enabled, the EDO for that service is loaded
  from the RM (if it's not already loaded), and then executed,
  the results being returned to the client
* If it's not enabled, the SM checks with the cluster manager
  to locate another node which supports the required service,
  and forwards the request to that node.

Is the general mode of operation you guys envisioned?  If so, I can 
try to flesh out the design a little more.  If not, let's discuss!
