IIRC exactly _this_ chatwindow to resource binding was discouraged.
Could clients developers take voice here? I do remember snoring, that
they would need to ditch the resource to window binding code.

Is this behavior described in any RFC/XEP?

And this? OK. It comes from /jeff resource. But shows where?

In the window labeled "contact at example.com" (or any petname Sally had
given to this rosteritem) opened for Joe? These will be mixed with /joe
messages?

In a separate window? How should it be named? Two windows of
"contact at example.com"?
And if so, this would break functionality for normal users changing
resources. Every time I would switch /work to /mobile, the conversation
that is going with me to /mobile would appear in a separate window at my
contacts PC. Not nice.

I think there still is.
