A text description could be compressed. It would probably be a series of
numbers. If for example, a pattern repeats such as a row of three ones you 
can represent it with a single number. Their are other ways to compress the 
description. Remember, this is being done by the HTML editor.

Font degradability is a big problem. It is almost a printing problem. This is
really not my field. I think panose is the best solution. A base font could 
solve other problems. A database with a basic description of fonts would also

help. These solutions would not be complete but not as inaccurate as you say.

Of course, this only describes regular text. What about weird things like 
HTML math? I am working on a global description of a text. The main problem 
seems to be that it breaks at a variety of points. It really becomes a 
description of a series of squares and rectangles. The descriptions is not 
meant to only describe text. So I am considering other ways of describing a 
variety of data. I am sorry if it seems incomplete but I am working on it 
right now.
