Presence and IntComm WG

[Jeremy George <>]

  Excellent! And funny, definitely in the running for the deely-boppers.

  I agree, a rulemaker would need to provide guarantees of privacy.
In a mall scenario, the mall operators might even lend locators
without charge provided the lendee is willing to accept advertising
offers.  When dear old dad passes the hardware store the locator
announces a two fer on screwdrivers for the next ten minutes.

  The search party in the woods is iffy, unless the woods is a WiFi
hot spot :)
