Sharing data between workflows

Dear KNIMErs,

As usual, just a quick idea/suggestion for your development backlog lest I forget. :-)

To my mind, it would be incredibly useful to bridge the workflow boundaries, either via copy&pasting (as I previously suggested) or, more structuredly, via "entrance" and "exit" nodes for data.

This would open up a whole new world of possibilities - and complexities, as I'm well aware. However, the necessary meta-layer could be useful for metadata management as well, e.g. for finding nodes across flows (which would require and/or enable flagging and tagging).

Cheers

Oh, and yes, I'm aware of the disk swapping option, I'm using it right now. However, it'd still be nice if KNIME could do it in a more abstrct manner.
