Dear Wesley and All,

Maybe someone can comment on whether alternatives like TFRC

We are currently looking into alternatives to LEDBAT for the PPSPP.
The majority of CCs will require some small modifications to the content
of the DATA and ACK messages as defined in the draft.

I also would not think it wise to change to something else

We will also run some large experiments in a controlled environment to
evaluate the effect and feasibility of the different solutions.

Regards,
    Riccardo and Arno
