Obama cold-shouldering Putin in Russia at next G20?

Not gonna happen.  The die-hard anti-Russia oldies still hungering for the good old cold war days will  have to go on hungering ... maybe even to their dying day.  One does  not have to be in a one-on-one meeting to say and opine on whatever it is one wants to say and opine on when in the company of everybody else at the G20.  Two people can talk to each other even in a room full of hundreds and still manage to keep that conversation from reaching the ears of people beyond them.
