[Olsr-users] Meraki's distance display - very nice

Hi Henning,

I thought that perhaps with dynamic ACK (like in the Ubiquity HAL for
madwifi) it might be possible to estimate the distance based on the
automatic timings.

Still though - Meraki have it working now (down to metres) and its nice to
look at - it seems quite accurate although I haven't actually taken to
pacing out the distances between known nodes.
