What's the difficulty?  After I wrote, I remembered that
I used to do this when I was testing something with
various degrees of magnification.

I think it should work, too.  This will probably be too late to
help Matthias, but when I get a chance, I'll try to get it to
work for me.

I think this a better solution.  Any method will ultimately
just change the fonts accessed by the `\font' assignments
(or commands, or whatever they are), so I
don't see anything wrong with the method you describe.
Of course, like everything else, it could be refined.

I think it would be worth implementing a way of increasing the
font sizes for the sake of accessibility for the visually impaired.
A related issue is the size of graphics in the HTML output:  While
the text is scalable in a browser, PNG graphics aren't.  When I work
on my manual again, I'll try to figure something out.  Obviously,
I can't make the PNGs scalable, but it should be possible to generate
them in different sizes and load the correct size based on the value of
conditionals in the Texinfo files.
