Searching for Webbased MSWord look a like

Hello!

I want to implement wikimedia in our company and there for I would like
to use an alternate frontend. Problem ist, the most of the saff knows
MS Word and know nothing about html or Wiki-Tags. So I am looking for a
web-word-processor, someting like ajaxwrite
http://www.ajax13.com/en/ajaxwrite/ but which I can implement on my own
Debian Sarge Server. The important feature is, that users can
copy/paste pictures instead of uploading them.

Do you know something like this open Source?

Thx
Christian Maier
