javascript/ajax-only mode? (no php, asp, ...)

Hi everybody,
we are using FCKeditor 2.x for quite a long time in our web-application.
Works great and without problems. We also use the build in file-browser with
a self written integration/connector to our server-side-scripting language. (which is NOT PHP, ASP, ...)

We know have the idea to use CKeditor 3 instead but while evaluating it i've encounter
and wonder that there is no file browser included anymore.

Ok, let's use seperate product CKfinder instead. This should be easy beacause it's from the
same company. But i am very astonished, isn't there an pure javascript/ajax version available
for download?

I've tried the php-distribution with no success.

Is there a possibility to run CKfinder in a javascript/ajax-only mode so that it is totaly
independent of the server-side-technology? (as it was before with the file browser inside FCKeditor 2.x)

I've looked in documentation and have rewritten the connector for using with CKfinder.
I also configured the url's to my connector but without success.
There is always a php-side (source-code) to be shown in the main ckfinder frame when invoking the browse-server button

Can anyone give me some information or hints how ckfinder can be run in a php, asp-, etc. less
environment and how this can be setup/configured with ckeditor?

Thanks and Regards...
Bernd
