I'm now trying this and it seems to be ok (not working in IE 8):


var i,
     j,
     len,
     rules;

for (j = 0; j < document.styleSheets.length; j++) {
   rules = document.styleSheets[j].cssRules;
   len = rules.length;

   for (i = 0; i < len; i++) {
     if ( /font-size/.test(rules[i].cssText) ) {
       rules[i].style.fontSize =
         (parseInt(rules[i].style.fontSize, 10) / 16) + "em";
     }
   }
}
	
document.body.style.fontSize = "100%";


I search for font-size rules and then convert any to EMs based on 16 
pixels equals 1 em (the app only ever publishes font sizes in pixels).
