This would be an extremely useful feature for enabling interactivity in a large format conference or training room that is too large for just a Webex board. Yes, we have companion mode however, that only allows you to use 1 board in conjunction with a system. I am talking about enabling a touch screen display per codec output. You could then have three touch enabled displays that can control the codec and also allow whiteboarding and other interactive features. The world of collaboration is turning towards more interactive rooms. Because people have discovered the world of remote working, it is becoming more common to perform collaborative functions such as whiteboarding versus just normal video conferencing. We could also allow companion mode to have more than 1 board at a time but either way, having more interactive functionality is a must.
