Line of "browser only" low-cost PDA devices that communicate text and image without a cellular network.
(Of course better and newer models would also have voice capabilities, but that comes later.)
Start off with a walky-talky like pair of low-cost PDAs except you dont talk but can only "SMS" each other. (Sold as toy for kids).
Continue with Wifi or bluetooth to PC.
Use PC as relay station - connected to the regular internet in broadband. People can even get payed for giving the relay service. (works only for people in the local vicinity).
Within a short while you'll have people able to pass and recieve information on local networks around the world, without the need to pay the cellular companies.-- pashute, May 01 2006 Cybiko http://www.streette..._gadget/cybiko.html [BunsenHoneydew, May 02 2006] Baked. Cybiko-- BunsenHoneydew, May 02 2006 err.. Skype ?-- neilp, May 05 2006 Skype's not even close-- BunsenHoneydew, May 06 2006 Skype on my wifi PDA lets me do all of the above.. I think the expensive bit of a PDA is the screen, and wifi, rather than the on board applications.-- neilp, May 07 2006 Yup cybiko. so must I remove this? ;''''( [MFD]-- pashute, Sep 12 2006 Not necessarily. MFDs are judged by the admins.-- BunsenHoneydew, Oct 24 2006 For short range you could use Bluetooth. Bluetooth SMS is possible using calendarnotes which you send to your peers.
Might be a good way to communicate during a meeting or a class?-- Pellepeloton, Oct 25 2006 random, halfbakery
