Ditto. I'm not sure what it's useful for, but it's very odd. And odd is good.

It could essentially be used as a very cheap vps. Maybe for running a bnc, personal website, etc.

Maybe one small thing you could do is use it as a teaching tool for kids. Let them load up some sort of web service/site on it (that they helped create) and allow them to see it working locally. Then you would put it in a box and ship it half-way around the world, open the browser, and bam! I think that would be pretty cool and worth the shipping costs.

Or you could create a VM image and then import it into the cloud.

For kids, that won't be the same. It needs to be physical, something they can touch and see.

Maybe useful to host a VPN in Austria for free ?

Maybe that's exactly why they are doing it (for free, no less). Just to see what people will do with such a potentialy disruptive service and technology.

Maybe they have bigger ideas for RaspPi's future than I do.
