Add a script to your users continuous integration tool or even to their source control management. Whenever software is compiled or commited your script will search for imports in Go source files. If your script finds a forbidden package it should flag an error with a friendly message like this:
"You are NOT supposed to write full blown Go, but only Daniel's NearlyGo, that nowadays disallows importing package X, for your own good. In case you get angry please take out your pants and jump vigorously stepping on it again and again until you have your rage diminished somewhat. Only then, contact Daniel." -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
