I too sync the DCIM folder on both my wifes and my Android phone. My wife routinely fills her phone's storage with pictures and videos. I wrote a small script (on my home server) that automatically moves files older than six months out of the synced folder into my master pictures folder. Never have to worry about overloading a phone again, and when I upgrade devices it should be a snap to put the pictures back on her phone, she'll never miss a beat! Also I have two folders, Movies and TV Shows, each about 5TB which I sync to various comps around the world. Some are full-authority some are one-way. The only issue with the set up is the initial sync, which goes much smoother over a local LAN. Hopefully once I have enough clients running it won't be as taxing to my internet connection to add a new client. I am interested in the concept of setting up zombies on friends and families computers. It could act as a sort of payment for the tech-support I provide whenever I go home.
