More and more people have flat data plans at home. But what about when they travel abroad?

In Europe many people just buy prepaid SIM cards, but that isn’t really convenient if you are traveling just for a day or two. I’ve liked the concept of FON since I’ve first heard of it a few years back. The main idea is to share a little wi-fi bandwidth at home and roam on other FON spots for free. Brilliant.

I believe the same concept could be easily applied to mobile. Create an app that will be able to take advantage of the personal hot spot functionality that is present on most smartphones and limit access to people that are using the service. Voila.

It might not be the perfect timing yet, but the time for such a service is really close if mobile operators will not cut the roaming charges or if someone like Apple or Google does not implement a global data plan.

p.s.: if someone wants to go ahead and implement this I’ll be glad to share more thoughts.
