Hello,

This draft already received multiple thorough reviews in the past and is IMHO already in a very nice shape. Beside, it's been a long time there is an implementation of HARP (based on version 04) with support of both Home Agent switch messages and VHARP. The code is freely available here: http://software.nautilus6.org/HAHA/index.php

Some performance evaluation based on that implementation can be read in this paper:
http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4976739

As for the draft itself, I have a couple of minor comments:

- Some considerations should be added (in section 4.1) about the Hello interval field of the HA HELLO message. As HARP can work on the same link as well as distributed over multiple links, the Hello Interval should be carefully chosen according to the deployments. 

- Any specific reason why the MAC_HARELIABILITY_TIMEOUT parameter is prefixed with "MAC_"?

Thanks,
romain
