I'll start with a couple of things, and then Helen will provide a bit more information on the paper that we also released yesterday.
Over and above the regulatory document we released on the 700 megahertz and 2,500 megahertz, we also released a document pertaining to more specificity around tower-sharing.
I'd like to make two other points. One, in the Department of Industry we do a lot of things, if you look at the estimates. One area that we do defer to someone else involves health matters. The Department of Health has looked at this many, many times, has done a recent review, and has come to the determination that no harm would flow from these towers, so just for the record, if you wish to pursue that matter, I think the Department of Health would be the better place.
We're quite conscious of the societal challenge associated with these towers. Everybody likes the iPad, everybody likes the BlackBerry, everybody likes the iPhone, and everybody likes to have access, but nobody wants to have a tower in their backyard, for a variety of reasons.
By encouraging more tower-sharing, what we are trying to do is indeed reduce the number of towers that need to get built—
