I think we've done well in our collaboration with various international research entities. You don't want so much collaboration, though, that you end up with group think, because often it's the competition of ideas that leads to innovation and new insight. Just because two countries are doing the same study doesn't mean they're using the same technology or the same approach to try to get at the problem. Sometimes these competitive situations are quite healthy for spurring on innovation.
