I’ve been meaning to post about Whisher for a while but they just launched some nice beta software so it seems like the right time. The company is based in Barcelona and they showed me their alpha code back in February. Now, however, they’re ready to go live.

Whisher is essentially a metered hotspot system. You use their plug-in and see various hotspots on the screen. Instead of seeing an encrypted hotspot called “FARGLEBOXR” you will see a useful name and a price per minute or hour. As a consumer, you know exactly what you’re paying and as a Wi-Fi provider you’ve got an easy-to-use system for allowing folks to hop on without buying secret code numbers at the counter. They’re offering white-box services to providers who can rebrand a Whisher hotspot or simple pay-as-you-go accounts for cybercafes, etc.

You can also share your Wi-Fi for free and then pick up other hotspots anywhere in the world, similar to FON. This, combined with micropayments model, makes for an interesting product. The product is available now for OS X and Windows. You can download it here. Coverage is fairly sparse in the U.S. but it’s considerably more robust overseas.
