Text editors

[Simon Lord]

Has anyone successfully created a text editor with metacard for 
use in the following fashion:

I have a current need to create a simple text editor that runs 
*in the browser*.  This would be to replace the standard 
textarea tag that lacks any sophisticated editing capabilities 
whatsoever.  With metaCard's ability to run on the server, I was 
wondering what mc's limitations were with regards to create a 
.mt script that could allow for creating an inline editor into 
an html page.  Can mc interact with a textarea field in the same 
way it does *within* metacard?

Anyone even try this?  Samples?
