That depends entirely on the client. Jabber is a network protocol. It of
course sends XML messages to the client over the socket when such actions
happen. What the client wants to do in reaction to these messages (open a
window, play a sound, run a script, catch fire, whatever) is up to it.

Are you interested in writing your own client or using an existing one? If
so, which one?

Sure, the client simply lists the receivers in the <to> sub-element of the
<message> element. Read the protocol docs.

Formatting is done via XHTML. Again, see the protocol docs.

Again, client issues.

What does that mean? Obviously no client can do things that the server
forbids, like for instance getting the status of another user without first
