Real-time Updates of a Group Wall

Is it possible to use real-time updates from fac开发者_StackOverflow中文版ebook to get updates from a Group Wall?

NO. You can poll to FB's graph api how often do you need, but it's not yet "realtime"

So far only users, permissions, and pages according to their documentation. Although they plan to add more so check back with them or ask them here.
