Comment 1 for bug 656900

Looks like this bug was already reported, closed (which is maybe why I couldn't find it in a search), and they aren't going to add this feature. Why did Ubuntu switch to Empathy again? The developer's response was to write a separate application:

"This kind of things shouldn't be part of Empathy. It could MAYBE be done as a plugin but as Empathy doesn't have any plugin system (bug #547208) and there is no plan to add one for now, I'd say this should be a separated application. Now that Empathy uses MC5, I think you should be implement most of the actions in a separated application."
