Trying to think further, i stumbled on this idea: what about having
something like an _AGENDA suffix for properties that would make the
agenda decide whether it should get the entry or not?

For example, here is a todo:

,----
| * Try to avoid stupid examples
|   :PROPERTIES:
|   :WarningAtDay_AGENDA: <2007-11-11 dim>
|   :END:
`----

When getting entries for the agenda display, Org might an entry with
such a _AGENDA property. Then Org's job would be to check whether this
entry has to be included in the results or not. For doing so, it will
have to call a user-defined function like :

,----
| (defun org-agenda-get-entry:WarningAtDay (param)
|   ...
|   [Returns t or nil depending on param]
|   ...)
`----

If the function returns t (e.g. if the function above says that today is
later than the value of WarningAtDay_AGENDA), then the todo is included.

This way each user could (easily) define its own rules for deciding what
entries should appear in the agenda display.

But enough speculation for tonight :)
