At that point it seems like anyone could sign the contributor terms for CC-BY licensed data

I'm not sure about it (IANAL) but I'm not sure that helps. The terms say that you need to be the copyright holder or have their explicit permission, would being under a compatible licence count a "explicit permission"? I wouldn't think so, but I may be wrong.

Something that I just realised we may not have made clear before, is that "renegotiate" isn't the right term in a lot of cases. Recently CC-BY 2.5 (Australia) has become something of a de-facto standard for our governments releasing information that they want the public to use - although there are exceptions, like the National Toilet Map which is under a restrictive licence :(.

A lot of the data that has been released in the last month and a half (most of which we haven't imported or thought about importing yet) was made available without us talking to the copyright holders about OSM.

If it ends up that we need to go and talk to them all to get their explicit permission, then that's the way it is. It'd be nice not to have to, but it we can't make that kind of change without causing other problems, then there isn't a lot we can do about it. As mentioned in other posts, I'm more concerned with not being able to import data that people have had to make available under the ODbL anyway.
