Having read through come of the questions on here it's my understanding that v 1.0 of the API is for read-only access to real-time data, pretty much what's available in the data dump. Write support is planned for version 2.0. My question is, will version 2.0, or some future version after that, have a means to access the chat system? Specifically, what I'm looking for is a way for Stack Apps to authenticate as a user and post messages to a Stack Exchange chat room. Is such functionality planned?
