I have a follow-up question for each of the gentlemen here, if I can get it in.
My long-term concern is that if the technology begins to change and we rebuild essentially the same old structure, will we be going where the puck was and not where the puck is going to be? Is that a concern in that respect?
The follow-up question to Dr. Lockyer, which he can take afterwards, is this: what sorts of timelines are we looking at? Are these conceptual or are these timeline ideas that would be even more long term than your TRIUMF proposals?
