Hi Ramon,
Yes, this proposal would be feasible right now using atheros chips and
something along the line of madwifi (http://madwifi.org/).  But i am
sure anything could be rewritten in India for any hardware and be
open-source without any commercial company involvement apart from the
the low-cost hardware.
Question for me still is: why use only 1 channel?
thanks Fred
