<p>Found the answer. At this time there are basically two ways to implement it:</p>
<p>1 - Use <a href="http://www.omgubuntu.co.uk/2009/11/aero-snap-ubuntu-linux.html" rel="nofollow">this</a> or <a href="http://ubuntuforums.org/showpost.php?p=9207510&postcount=60" rel="nofollow">this</a> window manager hack</p>
<p>The hacks require modifying Compiz with custom commands or scripts.</p>
<p>2 - Use the <a href="http://wiki.compiz.org/Plugins/Grid" rel="nofollow">Compiz Grid</a> extension</p>
<pre><code>sudo apt-get install compiz-fusion-plugins-extra
</code></pre>
<p>Then enable Grid in the Compiz Settings Manager -> Window Management. </p>
<p>Grid uses modifier key + numpad to position windows around the screen, so it is not exactly aero snap, but is easier to implement, and works well.</p>
