and I propose another change, for UI friendliness:

<script type="text/javascript">
<!–
function ReloadTextDiv()
{
var NewText = document.getElementById("DynamicText").value;
NewText = NewText.replace(/\n/g, '<br />');
var DivElement = document.getElementById("TextDisplay");
if (NewText.length > 0) { DivElement.innerHTML = NewText; }
else { DivElement.innerHTML = "(blank)"; }
}
//–>
</script>

What is though is that textile doesn't work with live preview Traditional formating tags do.

Do you have a thought on that?

I searched here and there, but nobody seems to comment on it.

I believe the "Live Preview" plugin does this.

I think it could, but I am a scripting noob so I'd like to know what I get myself into.

Eventhough its an older post, I hope you don't mind me bringing this up.
