It's a very tricky problem - not only are there the problems you mention, but also if they're selecting multiple lines you need to draw three rectangles rather than one - the shorter top and bottom part-lines and the full lines in the middle. I've done it in the past (although in the end I didn't use it) by creating a function that homes in on the exact coordinates of the insertion point by adding text into a hidden field and using textWidth / textHeight (the tricky part is finding the start of the current line, the rest is fairly easy, although I'm not sure how you'd do centre-aligned text). It sounds hideous, but actually Flash is pretty fast at that kind of thing and it worked fine in real-time for reasonably short text. If your text is single-line, obviously it's much easier.
