We're working on (by which I mean I am working on) the invitation support for clients. The standard allows either, and we didn't turn it on because it was buggy, then months of other things dragged us away. It's really looking pretty nice now - the tricky part is safely processing incoming invitations, which I'm trying out a couple of different architectures to see what is most robust.
