Since Chrome has arrived I have been looking for a means to open directly into the "Ingonito" window.  Finally, someone has a script to do so.  Go to the following URL, copy and paste the script into notepad (naming it .js) saving it to a directory easy to get to (like your desktop).  All you have to do is double click and you're all set!

I came across this on Lifehacker. The script can be found at Michael T. Bee's ESI.

Updated Instructions

You need to put this JavaScript file into the directory containing chrome.exe such as:

C:\Documents and Settings\<windows user>\Local Settings\Application Data\Google\Chrome\Application\

Create a shortcut to the script if you wish to run it from the desktop or another directory.  If you don't do this you will most likely get a "file not found" error because the script cannot locate Chrome.
