For example, if the shortcode format is <!--[shortcode]--> or
<!--[shortcode ...]...[/shortcode]-->, in TinyMCE we can easily filter 
<!--[ to <pre>[ (or any other tag) on input and filter it back to <!--[ 
on saving/switching to HTML mode. It can also be filtered to 
&lt;!--[shortcode]--&gt; and back to <!--[shortcode]-->, etc.

The standard <![CDATA[ ... ]]> can also be used.

That way the shortcodes will be editable both in Visual and HTML modes 
and could be pasted, typed, etc.
