HyperScope is basically a port of Douglas Engelbart's Augment/NLS system on to the contemporary web. Augment, and therefore HyperScope, have _very_ deep hypertext abilities that might not be apparent at first glance, including a zoo of different kinds of hypertext options that can be combined in complicated ways. Layering this hypertext system on to the contemporary web, as a fully client-side Ajax system, meant alot of code. Dojo's package system helped to modularize and partition the pieces to make it more maintainable, and features like Dojo's event system, topics, XHR, etc. meant that we could make our code tighter and get more productivity.
