Michael W. McCormick in his blog, Enduring Legacy Genealogy, posted a link to a Get Satisfaction dialoge about the future of Family Tree Photos and its possible interaction with FamilySearch.org's Family Tree. Over the years, I have been shown a number of prototypes by developers, some with the assurance that I was looking at the "finished product." Most of the time reality sets in and changes are made to the proposed website before it is released. It is certainly possible that FamilySearch will implement these changes but there is never a firm timetable to programming and you might have to wait a while before the changes take effect.
On the other hand, I really like what I have seen so far of FamilyTree Photos and hope the program is adopted in a release version sooner rather than later.
