Exporting progress?

Hi,

I wonder if there is any way to report progress from inside a workflow to the outside. I can see several rather different approaches how that might be possible, and different layers of exportation, but I haven't found a good way to do any of them. Maybe they're not (yet) supported, but maybe I'm just overlooking something, or missing a (commercial) extension?

Here are the options I can think of:

  • Can I export custom progress from inside a loop, metanode etc. to the enclosure, overriding their default indicators?
  • Can I export custom progress to a web interface?
  • Can I export internal Knime progress to a web interface?
  • Can I export internal Knime progress to the eclipse progress indicators?

I know that I can "export" simple variables, but it doesn't seem like Knime has any optimizations to use this feature for this purpose. Or does it?
