Finally found a way to stream XBMC onto the Chromecast. Fairly simple setup and only one paid app at around $2.50 I think. Basically setting up AVIA to pass the streaming from XBMC to the Chromecast. Watched a couple of shows last night with no issues. This is for a phone or tablet not a PC. It says to use a nightly version of XBMC but it works fine on the stable Gotham release on my N7.
