Actually, that's a very tough question, to spell out the time. One thing I can say is that some of these issues are very complex. If you get into some of the discussions around transportation and take a look at mechanisms to ensure that some of the issues around producer cars are addressed—and in this regard Churchill was mentioned, as well as access to elevators—it will take a little time to work through those key issues.
The working group identified a number of issues, but a lot of their recommendations were that a process be developed to deal with them. I think it would take some time to work through that process.
