Micro scale radio transceiver for a sensor network demo

For a Micro scale radio transceiver for a sensor network demonstration, 
roI'm looking for a very small and light weight radio tranceivers capable of 
transmitting and receiving digital data within 3 meters radius.

Followings are desired specifications;
    Weight : Less than 5 grams (including battery, probably a tiny watch 
battery)
    Size     : as small as possible
    Operation life time : 5 hours operation with a new battery
    Bit rate : 9600 baud (or faster)
    Communication range : 3 meters
    Capable of operating in the presence of multiple other active 
transceivers of the same kind within 3 meters. This effectively means that 
multiple transceiver can simulataneously communicate with each other and/or 
a host. (It is acceptable if transceivers required to be  programmed to have 
unique addresses prior to experiments.)
    Capable of operating on a moving platform (including on a human or 
animal)


Any suggestion will be highly appreciated.

Regards,

Gustav Gorev
