DITA and Wiki Combo

What are your thoughts on whether wikis could be used for end-user technical documentation? I'd imagine that a more structured wiki based on DITA content (which may have already been created for end-users) might work well for technical documentation. Have you seen any good examples? I'd love to see a well-done example.
