FMD Server

I had the idea, of creating a server that stores the last locations of the Phone(encrypted and anonymous). The connection is optional and it can be possible to launch an own instance for more privacy.

What do you think? I will first concentrate to make the apps core features stable. But i think that this feature can be helpful in the feature. When the device is offline the locations are still available and it would also be possible to locate via a pc.

What do you think. And wich features would you like?
