Dear All,
I am sorry for keeping quite, as I am still
waitng for a verdict from the Motorola Research
Center. :)
I think eventually it makes more sense for us
to implement the destination option in the linux
kernel. However as I am not following the 2.3.x
development, I am not in the postion to comment
on the complexity issues.
Regards,
Yours Humble Mingliang
