[arin-discuss] tweak to proposed fee schedule

I agree that it makes a lot of sense and seems to incorporate the right
kind of incentives (for adoption of v6) without too much 'cost'. I'd
also like to hear, as Michael solicited, if there are good reasons not
to do this; absent them, this sounds like a good way to go.
