Erik,
I fully share your view, which is quite an advancement in the perception 
of what is a space infrastructure. Yes the platform should be considered 
as an infrastructure, thus re-usable for many missions. Only with this 
perception in mind could agencies make savings in the design / procurement 
of satellites.
Best regards, JFK

Adrian,

I only have one comment, slide 3 on the bullet that reads:

"Identify solutions and recommend to the IOP specific actions needed to 
facilitate cross-support of one agency's spacecraft/system by another 
agency's infrastructure;"

>From my perspective, at least in the exploration domain, the only 
entities that really are not infrastructure are the PI and the S/C 
instruments. I tend to view the spacecraft as infrastructure/a platform 
for instrument delivery enabling the PI to conduct tele-science/remote 
observations.  This perhaps becomes more readily apparent when considering 
a truly networked architecture whereby the spacecraft are plugging into 
and simultaneously supporting the infrastructure among groundstations and 
other spacecraft.  I suppose for manned missions we can consider the 
flight crew,etc  as users of the communication/navigation infrastructure 
somewhat analogous to the instruments on a robotic spacecraft (from the 
perspective of infrastructure usage).  It may be that I am making a 
mountain out of a molehill here -- I can appreciate that there are risks 
to making the ToR to narrow  -- but it seems to me that there is still a 
bit of struggling with the semantic definitions, conceptual model 
boundaries, etc. in working toward a definition of a cross support 
architecture that includes in-space routed communications.

Having said all that, a suggestion would be:

"identify solutions and recommend to the IOP specific actions needed to 
facilitate cross support between agency spacecraft and agency 
infrastructures, recognizing that the spacecraft themselves may part of an 
end-to-end interoperable networked communications architecture"

Best Regards,

-Erik
