I completely agree that there shouldn't be an expectation of an immediate reply and rather expect the exchage to be asynchronous. However, that renders to whole "presence indicator" moot, which is the subject of this particular thread.

If I try to talk to Bob and the expectation is that he might take a while to get back to me, it doesn't make any difference to know that he's "available" or "in a meeting". If he's available and coding he might not anwer for an hour. If he's in a meeting and bored he might answer right away.
