Official Accounts have also been in various IM programs. Meebo had a nifty implementation of this, but it has been done before.
Payments might be original, not sure. It is at least new to the US market.
Media Rich Sharing is also old hat, I recall YIM also having this to some extent. In the very least, they had games you could play with friends.
(Surprisingly enough, it appears ICQ never made a push into payments, which is odd since ICQ pretty much invented everything else about IM!)
