To go to the CAREN system for a minute, I was fairly involved with that in Edmonton, as you may know, and I've seen it in operation many times. It's a great piece of gear.
Last night I talked to the folks who were here at another meeting. They said they're mainly using it for research right now in Ottawa. In Edmonton, I think they're using it for some clinical work as well. How is that system developing in terms of it being used not just for research but for actual clinical work in difficult areas like PTSD? How is that coming?
