Why can't that case be handled by Slack + a collaborative drawing application?
Sure, with Slack you have the option of being ignored/receiver not noticing the message, but a remote-only company should have methods to discourage that. For example, people could set 'office hours' where they agree to be butt-in-chair for some chunk of time every day and actively monitoring Slack.
