I think no tech brokering is kind of silly
Tech brokering is how i keep from being on the bottom of the stack. I trade techs to one civ then trade the ones i just got to another and gett most of the techs that way.
To the OP, I normally giv my vassals all of my techs anyway, so its not really a problem for me. I find that they don't do anything but be a burden otherwise.
