I feared an answer like this. Thanks, no.

(excerpt)

   var getBrowserName = function() {
     return this.name = this.name || function() {
       var userAgent = navigator ? navigator.userAgent.toLowerCase() : 
"other";

       if(userAgent.indexOf("chrome") > -1)        return "chrome";
       else if(userAgent.indexOf("safari") > -1)   return "safari";
       else if(userAgent.indexOf("msie") > -1)     return "ie";
       else if(userAgent.indexOf("firefox") > -1)  return "firefox";
       return userAgent;

ugh.
btw weren't we all negative about browser sniffing? I'm doing my best to 
follow best practices and this NG is a big resource in this matter.
(Still learning, as all my life is about).

Uhm no, I'll not support people not able to correctly display a pdf in 
their browser. They can download the file and see it offline.

Apart the fact that this all is about a CMS-like system, the script part 
being a fragment of the total, the publisher decides what to publish and 
his audience, so if one comes and has no pdf support it is not my 
problem at the end of the tale, if not in a very indirect way.

Anyway I hope my question is of interest for someone else.
When it comes to "particular" questions this is the only place to go. 
Thanks!
Dan
