The Geek Beacon, the use of a Treo or cell phone with a bright screen to hail taxis, is really taking off. And I’m already hearing about plans for third party applications around the Geek Beacon concept (I’m not kidding...)

I spoke with a software developer on Thursday who wants to produce what could be a killer application, one that would take the Geek Beacon concept a whole stage further! I’m under NDA but, I promise that you, my loyal readers, will be the first to hear all the details when it is ready.
