Flexible Reward Inventory

Hello all
2 quick questions:
i) I am sure that representations are made to VS on the back of feedback from the V-Flyer forums. Does anyone know whether there is any possibility of VS introducing flexible reward tickets such as offered by Air France (used to be called opti-miles) or Continental (Easypass) amongst others? I am referring to the situation where you will get a reward ticket as long as there is a seat available, but you usually have to pay double the normal mileage if there isn't any 'normal' reward inventory available.
ii) Partially linked to the above, I want to go to Perth, WA in the middle of December on mileage but do not want to go in and out of Sydney with VS. Will my VS mileage allow me to buy the flexible mileage tickets on Singapore or will I be limited to the standard reward inventory? I want to go business of first.
Thanks
