I can't be very precise on that, but the answer is yes. There are a number of efforts in the U.S. to do this. There are people who have approached me in Canada to do this, who would like to see these alternative methods pursued. It's a mixture of expertise that has to come together to decide whether it's worth while.
We've been discussing at TRIUMF whether we should have a workshop or something like this that brings together the expertise of the accelerator community, the chemistry, the radio-chemistry, to see just how viable these other methods are.
So the answer is yes, everybody is looking at it. There's quite a bit of interest.
