Browsers are "smart"- they won't let you select text that's 100% transparent. 99% transparency works... but also looks kind of weird if the texts don't overlap perfectly.

You can roll your own text selection in javascript (on top of the bitmap) if you know the glyph positions though- that's what e.g. Google Books does. It's a valid option if you don't care about zoomability.

Are you sure? I just made a quick test and it works ok in FF, Opera, Chrome, Safari, IE9 (Windows 7, Ubuntu 9.10):

  <body style="background:url(image.png)">
   <span style="color:rgba(0,0,0,0)">Hello world</span>
  </body>
