Summary of follow-up tasks

• publish wiki, Done
• "recipe" for ideal node to re-broadcast 5Ghz AirMAX signal to local "internet cafes"
• Make PCEngines/Soekris image for ESD & BO router with ath support
• patch for 802.11 NAV setting (alternative to CTS/RTS) for AP non-AirMax nodes
• patch isc-dhcp to send multiple responses instead of typical 1
• research cone vs. symmetric NAT (looks like pf is symmetric; use same initially allocated port/IP tuple)
• research 802.1q 802.1d support (ebtables has --vlan-prio option, usable?)
• research iwconfig Ubiquti data rate setting (don't offer 1, 2, 5.5Mbps in bitmap for beacons)
• Ethereal patch to see timeline display of different data rates by time
• Network optimizations:
  • URL as SSID network name instead of captive portal (ie: www.playa)
  • Week long DHCP leases
  • single NAT router, multiple DHCP servers
  • disable lower data rates
  • ebtables on AP's to filter all broadcast traffic but ARP and DHCP
