Ask yourself if any of the things you mentioned actually result in a materially significant improvement in delivery of working software, in comparison to say... sticky notes and sharpies.
You start with sticky notes and a whiteboard, and then you note that nobody remote can change the whiteboard unless somebody else does it for them. And when you work from home, you can't see the updates unless someone sends you a photo. And Ralf's handwriting is terrible.
So you look for something that replicates the whiteboard on the web, and it's either too freeform or too rigid or too expensive...
I think it's incredibly obvious that just about any tool that can used remotely will be orders of magnitude more effective and helpful than sticky notes.
