Opening Google Earth (*.kmz) files with the browser

I already knew that Google Maps shows KML file content at its website. You only need to put the KML's URL at the following site search textbox:

http://maps.google.com

then execute the search. But I was unaware that the same applies to Google Earth's KMZ files. They seem unreadable without Google Earth, but you can use the same method above or use the following one:

Example KMZ file:

http://www.gearthblog.com/kmfiles/lasvegas.kmz

Append at the beginning of the above URL:

http://maps.google.com.br/maps?q=

The result is:

http://maps.google.com.br/maps?q=http://www.gearthblog.com/kmfiles/lasvegas.kmz

Open it in your browser.
