Consider adding unpublish function

[jamesplease]

For when things are being destroyed. It would be tedious to to keep track of all of the things that you've published, though. Ideally you would unregister all of your associated variables at once.

// yuck
futureVars.unpublish( 'myName' );
futureVars.unpublish( 'yourName' );
futureVars.unpublish( 'dogName' );

// better
futureVars.unpublish();

This would require keeping tabs on where things come from. One solution would be registering things under a name, which would only be used for unregistering.

futureVars.registerUnder( 'moduleOne', 'myName', 'Jmeas' );
futureVars.registerUnder( 'moduleOne', 'yourName', 'Someone' );
futureVars.registerUnder( 'moduleOne', 'dogName', 'Skip' );

futureVars.unpublish( 'moduleOne' );

This would require keeping a store of all registered variables internally.
