Impossible? Isn't this the responsibility of the assistive technology? 
ZoomText and Majic are just a few of the magnifiers that handle this all 
the time.  The "chrome" of the browser also has some of the responsibility 
- for example the zoom feature in the browsers.  The point here is that 
the client is doing the magnification, not the server that is sending the 
HTML in a Web based authoring tool.  Another point here - the requirement 
or need of authors with low vision is valid, but the placement of the 
responsibility of the solution on the authoring tool vendor is not, in my 
opinion, correct or most efficient.  That is the role of the assistive 
technology.  Only the enablement of the authoring tool to not prevent the 
use of magnifiers and zoom features is required here.
