aloha, joshue!

i think we should think in terms of '''equivalent content''' 
and '''repair content''':

1) equivalent content provides an alternative to a uni-modal object 
which may not be supported by the user's current working environment, 
such as using a locked-down system at a public access point or corporate 
or educational intranet, using a text-only browser, turning off 
image-loading to speed download of documents, etc.

2) repair content, then, is the choice of content available to the user
to provide a means of ensuring that the equivalent content is exposed 
in a manner appropriate to the requesting UA's configuration and 
capabilities, as well as subject to user preferences and actions. 

The difference between the twain is that equivalent content is precisely 
what it's name implies; repair content is, then, the most appropriate 
form of equivalent content for the requesting UA and the end user.

LANGUAGE, n.  The music with which we charm the serpents guarding 
another's treasure.     -- Ambrose Bierce, The Devil's Dictionary
