I understand the need. Watching while typing is very different from composing notifications. It is a feature many people want. It works great in LLuna. You can see many people typing into their chat bubbles simultaneously.
Unfortunately in Jabber it is really a waste of bandwidth, because of the message envelope of 150-200 byte. Only the envelope (without payload) every 500 ms can hit the karma limit.

I agree. This feature can only be standardized if we find a specific optimised protocol. Any simple message-with-special-tag-and-namespace based approach is a waste of bandwidth.
