[newbie] WebDav - Content Negociation

[JY]

I want to make a simple wiki where pages can be edited by WebDav. 
Several formats can be available.

For example: The page http://example.com/main can be modified by one of 
this file :

/
|- main.html (for modifications with an HTML Editor like DreamWeaver)
|- main.doc (for modifications with MS Office)
|- main.odt (for modifications with OpenOffice)
|- main.wiki (for modifications with Notepad with Wiki Syntax)
|- main.pdf (read-only PDF format for export)

Can Sling help me to do that?
