Judgement has been reserved. I haven't idea what that means in terms of time frames, etc.
I've spoken to a few experts in the field. None of them give us much hope. The only hope is that these things are yet to be tested and thus the interpretation of them is still a little more open then it would be in a few years time. That may assist us.
For my money, this is one of those shots that you take and if it comes off that's a bonus. If it doesn't, you're no worse off than where you are anyway.
