<br><tt><font size=2>Hi Pete and Nancy,<br>
</font></tt>
<br><tt><font size=2>Given that we keep AvailableResources as a top System
element,<br>
I suggest the following conclusions:<br>
</font></tt>
<br><tt><font size=2>(1) A ResourceService MAY be started using SystemControlService<br>
(or via factory installed configuration)<br>
- but a System NEED NOT support ResourceService</font></tt>
<br>
<br><tt><font size=2>(2) At most ONE ResourceService may started on a given
System<br>
- that is, no partitioning of Resource types is allowed across</font></tt>
<br><tt><font size=2>different running instances of ResourceService<br>
- this preserves the administrator's tight control of installed</font></tt>
<br><tt><font size=2>resources, especially firmware<br>
</font></tt>
<br><tt><font size=2>(3) The installation of temporary Resources (e.g.,
Job-scope scripts)<br>
by End Users is OPTIONAL and MUST require strong access<br>
control if supported<br>
- otherwise it's not feasible to verify a Trusted System MFD</font></tt>
<br>
<br><tt><font size=2>WDYT?<br>
