[Typo3] accessible font size?

This could work... 

Another approach that just popped into my mind (without thinking it 
through, though): Let the "change font size"-Icons pass some parameter as 
GET-value. Check for that parameter in TypoScript, if it is set, invoke a 
little PHP-script (user-function) that stores the actual fontsize-value 
in the users session data. Every user browsing a TYPO3-made site has a 
session, regardless if he's anonymous or logged in.

Now implement another user-function that modifies a small stylesheet, 
setting the actual (base) font-size based on what's stored in the user's 
session. Something like 

* {
    font-size: [whatever];
}

should do if the rest of the elements is sized using "em". Of course, 
this stylesheet should be the first on every page.

But frankly, I think your approach of just using TypoScript and no user-
functions seems to be more sexy. I'll try that soon, for I need to built 
exactly that functionality into a new site.
