zoo daemon sends package list over wire

man. long live google protobuf. It's amazing. This
	thing just sent all 3k of the package info over http in raw
	wire format. I'm sure this isn't neat to anyone young but
	to old hacks like me, it's fucking magic how wonderfully
	advanced the language and codebase is. It just reminds
	you how there are actually beautiful things in the world.
