Hi Balbir, Mini summit is still few months away. I think a better idea would be to try to thrash out the details here on lkml and try to reach to some conclusion. Its a complicated problem and there are no simple and easy answers. If we can't reach a conclusion here, I am skeptical that mini summit will serve that purpose. Thanks Vivek
