People affected by California wildfires get and send firsthand information using micro-blogging service Twitter. Usually during emergencies, all telecommunications networks get overloaded due to huge communication flow increase in all affected areas.

2004 Tsunami taught us that when telephone landlines do not work anymore, mobile network is overloaded, short-messages (SMS) were still going through, but often with up to a hour delivery delay (better than no communication).

One of the most critical problem to solve during emergencies is how to spread information on both directions (from affected people to emergency services and from helpers to victims). In addition, affected people and their relatives are in need to get in touch.

In California, the American Red Cross, among others, have open 2 Twitters threads. One is made to push information out (e.g evacuation routes) and the 2nd one is "Safe and Well" which provides a way for affected people to register as “safe and well.” using a list of standard messages.

Concerned relatives can search the list of those who have registered themselves as “safe and well.” directly on American Red Cross website.

AirTalkr is another multiple IM client application immediately available in its beta version for Windows, Linux , Mac OSX as well as on Web-based version.

IM supported protocols are MSN, ICQ, GTalk, Yahoo and AIM but AirTalkr also connects you to your YouTube and Flickr accounts. In addition, AirTalkr creator Hu Shunjie comes with an interesting concept called "AirCards". AirCards are profiling cards where you can add of your buddies information such their Twitter and blog updates, their photos on Flickr as well as their profiles on MySpace and Friendster.

AirTalkr is a very light application but requires the installation of Abobe Integrated Runtime (AIR) which enables developers to use Flash, Flex, Ajax and HTML to create rich interface applications.

The AirTalkr version is still beta and some bugs have been reported but I personaly like this very smooth application and really looking to see what will come next (Skype, more social networking plateforms supported, etc..)

It definitively worth a try. Did I mention that AirTalkr is free and totally Ads-Free (Thanks Hu!).

Whisher, a Spanish start-up, backed by Switzerland’s leading phone company, Swisscom, and the venture firm Benchmark Capital Europe is apparently very active for few month now. The principle of Whisher is that Wireless Access to the Internet should be free and accessible from everywhere which is basically the same concept than FON Movimiento, except that you don't need to purchase any specific hardware.

Whisher' users are requested to download an application through which they can share their wireless access (works also with WEP or WPA connections) with other Whisher members 

The newly released version 2.0 beta of the software offers more than just storing and encrypting connections' passwords such:

• Wireless connection manager
• WiFi sharing
• Chat with other users connected on the same wireless access point.
• Multi Instant Messenger support (Yahoo, MSN, AIM, ICQ, GoogleTalk, Twitter, Jabber)
• File Transfer (with users sharing the same wireless AP)
• LAN Support
• GeoLocation
• Other Networks connections (access via commercial access; hotspot, etc..). FON is supported too.
• Around You. Gives you informations about coming events, restaurants around the wireless connection you are currently using.

New services that should be available soon :

• Voice Support
• Global File Sharing 

Plateform supported : Windows XP, Linux, Mac O/S. Vista not available yet.

The software is still beta and some stability and registation problems have been reported. More information on their Blog
