The recommended configuration for mid-to-high-end school servers has 3
active antennaes attached, and our recommendation is that they are
placed well apart. They can be up to 10m apart due to USB cable lenght
limits, and Wad mentioned 2m minimum recommended distance. If the
distance is enough (in relation to the granularity of timers in the
antennaes) then telling the XS about relative location of the
antennaes could provide enough info.

Having said that, I suspect that being able to do any of the above is
somewhat far ahead in time ;-)

cheers,
