Want to use ripple locally? Disabling websecutiry is bad for browsing but you can launch a second instance of chrome with a different user-data-dir.

ripple_chrome

#!/bin/sh
# This only works for OS X but could be easily adapted for Linux by changing
# some directory names.
IC_TEMP_DIR=/tmp/icdir
rm -rf $IC_TEMP_DIR
mkdir -p $IC_TEMP_DIR
cp -R ~/Library/Application\ Support/Google/Chrome/Default $IC_TEMP_DIR/Default
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
	--disable-web-security \
	--user-data-dir="$IC_TEMP_DIR" \
	--app="http://localhost:8000/?enableripple=cordova"
