I'm going to be driving to a wedding (long story, don't ask) during the BYU / Nebraska game. Does anyone know if it will be available to watch online?

I know most the ESPN stuff I can watch online by logging into my Comcast account, but where this game is on ABC I'm not sure if I can still do that or not (yes I know Disney owns both ABC and ESPN but I'm not sure that means the online viewing works the same way on both channels).

Any ideas?
