IP/Human

The somewhat contentious inclusion of Radio Frequency Identification (RFID) tags into clothing and other products provides a new, but somewhat slow, method of communication: "Transmission of IP Datagrams on Human Carriers". Whilst this falls under the same umbrella as the 1990 April Fools Day RFC for transmitting IP over carrier pigeon, it is still possible and probably quicker.

RFID tags provide a mobile media that can be both written to and read from when in closer enough proximity to the appropriate hardware. Each person could have one tag per item of clothing which makes multiple potential carriers for the IP packet. The RFID tags (and the carrying human) will be moving in a pseudo random path and there is no guarantee the packet with reach the its destination. There isn't even a guarantee the IP packet will even go in the correct direction! This will introduce high packet loss into the commutation channel.

Higher populated areas are likely support using RFID as a base to communicate better than less dense ones. Another area of research will be the “higher bandwidth” airline cargo. If there is an RFC for the transmission of IP Datagrams on Avian Carriers why not a standard for the “Transmission of IP Datagrams on Human Carriers".
