I also created an Awesomium wrapper couple of years back, but at the time i concluded that(dont really remember why, there was couple of different things) rather than using awesomeium it could be a better idea to use the Chromium Embedded Framework(used in many mainstream apps, like steam). I do not know how far both are advanced now but anyway you could also check it out.

ps. my vip version at the time: http://www.youtube.com/watch?v=drq6uHHM7TA
