In the first TinyMCE compressor, the cache was invalidated only by some 
of the settings. That was fixed a few weeks ago, so now it is 
invalidated by any change in the init array.

The filter "tiny_mce_version" passes the version number as a string. It 
can easily be changed several times by different plugins. All of these 
will work:

function my_refresh_mce($ver) {
   $ver += 3; // or $ver .= 3; or ++$ver; etc.
   return $ver;
}
add_filter('tiny_mce_version', 'my_refresh_mce');

I'll add this to the codex too.

I'm more concerned about how to allow a plugin to use the same 
translation method for TinyMCE as WordPress, specifying langs/lang.php 
that can be translated with the standard WordPress functions and loading 
that instead of langs/[lang].js and langs/[lang]_dlg.js.

There are several ways possible, but all would require some more coding 
on the plugin's part. If you are interested in testing this, perhaps 
it's better to take it off list, as not many people would be interested.
