Tools that enable collaborative, networked "white-boards" of various kinds. Of course the best kind would be for all parties to have a physical white-board such that when anyone draws on theirs, the other parties all see the same thing; things like this do exist but are expensive.
Wikis can be seen as a VirtualWhiteboard tool where the contents of the white-board is limited to text (and atomic images, i.e. you can put an image on a wiki, but others can't edit the image itself through the wiki software). But perhaps a wiki could work with ScalableVectorGraphics.

- [COLER] A tool for collaboratively constructing entity-relationship diagrams
- UMLWiki. This product has not, to my knowledge been created, but has been suggested by DennisDaniels
- Anyone know of a tool which is a simple drawing program, like MacPaint, where multiple networked people see the same thing?
- There's a [white-board plug-in for JSPWiki]
Slightly off-topic, but the Wiki:SelfLanguage has a sharable communal interface. I wish operating systems would support collaboration and community a whole lot more, to start with making Person a first class object.
