I couldn't find it currently, or any tasks that seem to relate, but an awesome thing to have in Phabricator would be some kind of webhook support, very similar to how JIRA/Bitbucket/Github do it:
https://developer.atlassian.com/jiradev/jira-architecture/webhooks
https://developer.github.com/v3/activity/events/types/#commitcommentevent
Would be amazing to get real-time update via an IRC bot that exposes endpoints for the Webhooks to call. Was one of our favorite things from JIRA/Bitbucket that we used before migrating over to Phabricator.
