This answeralert stuff is quite useful.

The document talks about it's applicability to Push-to-talk.

I would also like to see a mention of it's usefulness for other
features.

In particular, you can use it for Intercom call features (like on
any traditional PBX).

Also, it would be extremely useful to allow the answer-mode to be 
allowed in an UPDATE (and re-INVITE). That would enable many features
that are available today on traditional PBXs (secretary override, and
other fun stuff difficult to do today).
