I've thought about this since yesterday, and the simplest
kind of 'partner' that I can imagine for a 'ToDo', would be
a 'Deliverable'.

A deliverable would probably have a title, it's own 'Done'
boolean property, and probably an optional DeliverableURL
property. I'm not sure if it would need it's own 'Doer'.

ToDo would need to be reworked so that it's 'Done' property
could only be set if all associated Deliverables (if any)
were also done (Steve McConnel (sp?) calls these 'binary
milestones').

What do you think, is that simple enough?
