I looked at Chromeless too but it doesn't seem to be regularly updated, which is really important since browsers are moving fast.
Awesomium also needs an update or two, since it still doesn't support WebGL, Web Audio API etc.
I guess in conclusion, for now as far as wrappers are concerned, nothing's quite there yet. Perhaps ironically the only way that would work is installing IE9 and using the IE ActiveX control :P
