No, we provide a one way stream.  Some congregations have found it effective to allow the friends to email / text comments to the conductor or another attendee and have them read or even a recording played into a microphone.  To allow for a smooth viewing experience the stream is delayed and therefore a normal delay of 30 to 50 seconds can be expected.  If you wish to have a live meeting with comments, check out Skype for business, Uberconference or Zoom.  You can also broadcast live the above mentioned services to Live Kingdom Hall for those that may not have the technical experience to setup a live conference.  Though they would not be able to interact they can still view the live stream.
