I think I have found a way to install this beautiful editor on a subdomain(serve files from subdomain) and make it working on any page from main domanin.
I saw that some has got into trouble regarding this and I did it myself yesterday.
So the solution.
file: wymeditor/iframe/default/wymiframe.html
add line in <head>: <script type="text/javascript">document.domain = 'domain-name-where-you-want-to-use-editor.com';</script>
and modify the path to the wymiframe.css file so it looks like http://static.domain-name-where-you-wan ... iframe.css
file where you use editor:
add line in head:<script type="text/javascript">document.domain = 'domain-name-where-you-want-to-use-editor.com';</script>
include next files:
<script type="text/javascript" src="http://static.domain-name-where-you-want-to-use-editor.ro/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="http://static.domain-name-where-you-want-to-use-editor.ro/path-to-files/jquery.wymeditor.js"></script>
<!-- lang file -->
<script type="text/javascript" src="http://static.domain-name-where-you-want-to-use-editor.ro/path-to-files/lang/en.js"></script>
<!-- skin files -->
<script type="text/javascript" src="http://static.domain-name-where-you-want-to-use-editor.ro/path-to-files/skins/default/skin.js"></script>
<link type="text/css" rel="stylesheet" href="http://static.domain-name-where-you-want-to-use-editor.ro/path-to-files/skins/default/skin.css">
note that you have to add lang files and plugin files and skin files by hand. They can not be included with ajax...
After this call editor like:
<script type="text/javascript">jQuery( function(){ jQuery('.wymeditor').wymeditor({basePath:'http://static.domain-name-where-you-want-to-use-editor.ro/path-to-files/'}); });</script>
Hope it helps
