I'll take a stab at the first question you asked, and others may wish to comment.
I think that at this point a funded mechanism for the G-8 initiative has not been determined, as I understand it. Therefore, what really needs to be determined is how the commitments that were made last year will be met, with whatever funding mechanism is put in place, given those who will be contributing to it.
I think when we look at how other funds, such as the Global Fund, work, as I understand it--and I'm an obstetrician and gynecologist and not an economist or a finance person--what happens is that this is really country-driven. In other words, a country has a plan, it establishes its priorities, and it applies for funding to a fund. That's one scenario.
Obviously, specific bilateral relationships are a little different, and it depends which one we're speaking of.
