The way I read it Jill
Any records office/genealogy organisation/family history society that would like to put its genealogy images online
a) Will have the records digitised at a minimal cost by the LDS Genealogy Society
b) Will be responsible for creating its own index to same
c) Will NOT charge people to access the index - a copy of which will be on familysearch (and on the home website)
d) Will have the images on their home website (with assistance from LDS if required) & may charge a fee to see the full image.
The theory, with which I tend to agree, is that they have developed expertise in digitising/imaging and will share this expertise with whoever requires same.
My imagination looks at the A2A catalogue - you do a search & then request the scan of the found item - rather than have to travel 10 000 miles to see same

Apologies if I have some of the detail incorrect
