It's very possible. Let's start with a dev browser.
Step 1: Download Chromium
Windows -- http://www.chromium.org/getting-involved/download-chromium
Mac -- http://www.macupdate.com/app/mac/36244/chromium/
There should be a build ready to go, but these locations change over time. So if these end up with 404's do a Google search for Windows Chromium Download and you'll find it.
Step 2: Then run the executable with this flag after it. --disable-web-security
Windows -- Create a shortcut to the executable and tag this in the Properties. Or run from [CMD].
Mac -- Open up a terminal and run this straight from there with the flag.
And, you should be good to go. I also setup a quick Apache service and run through a 127.0.0.1 configured domain, but localhost should be just fine. Here's proof.
I hope this helps you!
