One of the biggest problems with using RW live at the table is when you're switching from nontactical activity and time which RW handles beautifully with its fog of world feature and tactical activity and time which RW simply punts on. The ability to integrate with a VTT would at least let you export a partially revealed map to the VTT and place the party on it and begin tactical movement from there using the VTT's lighting and reveal features and that is before you start tracking init and status effects.
