Almost everything cut by tree services around here is chipped and either sold to a wood chip power plant or it's sold to make wood pellets. Normally they show up with a truck with a chipper in tow and as branches are cut off they go right into the chipper. I've heard (but can't confirm) some of them can chip a 24" diameter tree. I don't know how popular pellet stoves are down there but a number of companies have popped up that focus just on pellets. If it's a bad winter they will have trucks lined up. As the bagged pellets are put on a pallet they go right onto to a waiting customer's truck.
Off topic but If someone came up with a viable way to dry wood chips and design a wood stove that could feed them from a hopper like a pellet I would switch over in a heartbeat.
I think that you would want to dry the wood before you chip it. There are boilers out there, but most of what I have seen is for large buildings. Although it wouldn't meet your criteria for self feeding, I have often wondered how a coal burning stove would be for chips.
