I have to say that our involvement in this activity with Public Safety Canada and Corrections Canada is really very much at the beginning stages. We've had a number of meetings to outline what we might be able to bring to the table, so we're actually just getting started looking at these sorts of things.
There is, obviously, an initial range of devices that one would consider looking at. GPS-enabled devices, devices that just use radio frequency information, and biometric devices, for example, can all play a role. The real issue, as I said in my opening statement, is for us to get a better understanding of the operational requirements, so that we can then transfer those into technical requirements and assess those technical requirements against the devices that are currently available.
