Which browsers, if any, support Object.observe? I'm surprised I'm unable to find any info on this.
(And are you aware about any estimated times of arrival for this feature?)
About Object.observe: "Object.observe allows for the direct observation of changes to ECMAScript objects. It allows an observer to receive a time-ordered sequence of change records which describe the set of changes which took place to the set of observed objects." — see ecmascript.org, the Solution section.)
Edit November 2015: Apparently Object.observe has been cancelled:

Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it. The Object. observe() method was used for asynchronously observing the changes to an object.

You can use kangax's Browser Compatibility Table for Object.observe
It is part of ECMA Script 7 Specifications, it seems. Luckily, at the time of this writing, my current browser, Chrome 33, is the only one which supports it :)
If you like to enable it in Chrome 33,
Visit chrome://flags/
And enable Enable Experimental JavaScript
