The idea i had was that the mobile agent to be a
plugin module to any part of VRS including the
middleware.  The mobile agent uses a published API of
the middleware to provide a range of services.

If we the use the above approach, the mobile agent
will not be accessing the physical machine but the
sanbox within which the VRS is running. 
The usage of the mobile agent can be further extended
to handle aysnc control messages used within the
cluster.

Does this make sense?
