I'm not sure exactly what you're asking, but my general feeling is that since we've worked so closely with MDS Nordion in the past, in anything we would do we would want them to be involved, because that's their business. They're experts on many aspects of it. As you know, there's a business model associated with it, and it's not only the production issues.
I think you can produce it, but that's not the issue. The issue is if you can produce it pure enough. Then, all the other things being satisfied--meaning cost, for example--would be a big factor.
