nit: do you guys know about the short form of this statement? As in:
/** @private {remoting.AppLauncher} */

I personally prefer it.

Glad to know.  I love it. Done.

Why can't this be just null? It's never disposed of.

[kelvinp, 2015/02/04 00:38:13]

It is artifacts from a previous experiment.  Removed.
