Hi Pete and Nancy,

Given that we keep AvailableResources as a top System element,
I suggest the following conclusions:

(1) A ResourceService MAY be started using SystemControlService
     (or via factory installed configuration)
     - but a System NEED NOT support ResourceService

(2) At most ONE ResourceService may started on a given System
     - that is, no partitioning of Resource types is allowed across
       different running instances of ResourceService
     - this preserves the administrator's tight control of installed
       resources, especially firmware

(3) The installation of temporary Resources (e.g., Job-scope scripts)
      by End Users is OPTIONAL and MUST require strong access
      control if supported
      - otherwise it's not feasible to verify a Trusted System MFD

WDYT?

Cheers,
- Ira
