i hope we aren't polluting the wrong people's mailboxes with this 
conversation. sorry if we are :)

right. we need to be able to associate svg drawn shapes with data so the user 
can click on something (like a class or association) and select it. we aslo 
need to be able to associate widgets with UML geometries and standard 
semantic metaphors. then there's that whole extensibility thing (being able 
to create new visual metaphors for new concepts, like aspectJ aspects).

i thought that in previous discussion, we had admitted the requirement for 
free-drawing capabilities - to a degree. i think it would be worthwhile to 
allow developers to add miscellaneous text to a diagram and maybe simple 
block shapes and what have you.
