I will probably start after the feature freeze in eclipse. June sounds
+- right.

Me probably. ;)

Same objective here.

Ideally the view registers a listener with the model and perhaps also specifying some hysteresis (so it is notified on a block of events, not every event), and then when it is notified it can update (optionally subject to an "update policy" selected in the view, as is often done with debugging)
We don't support "Live" trace reading yet. I'm not saying it won't work,
but it has not been tested.

When would you be available to work on this feature, I would love to
sync up our efforts for this.
