Google Glass needs an update

On Apr 4, 2013, Timothy Jordan from Google gave developers at SXSW in Austin, TX a sneak peek at the Google Mirror API, which is what they'll use to build services for Glass (see YouTube).
A few years ago I experimented with Layar, an app for augmented reality. As AR will be best experienced using see-through devices, I was excited when Google announced their Google Glass project. But, to be honest, after watching the mentioned video, I am a little bit disappointed.
My dissatisfaction focusses on the following 2 key points:

1. Google Glass is not a see-through device at all. It is a tiny screen in the corner of your eyes. Adding digital information to real world objects is not possible. This is one of the main requirements for augmented reality.
2. Google Glass can only be used by programming Google's Mirror API. That means that every bit between the glassses and my application will pass Google's premises. I must admit, it is the very same architectural model Layar uses for their app. But Google is not the company to be trusted about privacy of your data and that didn't count for Layar a few years ago. Having a mandatory man-in-middle service is a little bit scaring.

So, my pred-ICT-ion is, that if Google Glass will break through to the masses, it needs an update. It should have real see-through capabilities and the Google Mirror API would allow to be bypassed for certain data transfers between the glasses and your application.
