This is an outstanding idea and distinct from current GoogleDocs or other wiki implementations precisely because it's asymmetric (one owner, many commenter/editors). I think you could enable a business model based on remote copy editing by 3rd party labor where the owner has the ability to accept or reject the changes. I can definitely see this as being offered as an alternative to the basic browser WYSIWYG editor for blog and wiki systems where the user ask for help with final edits or copy editing. I see a lot of potential for this. We did some research a while back for a wiki startup and this supports a mode that some prospects were asking for which wikis today do not support: an individual owns the page and can accept or reject additions/edits. This is different from the wiki model but appropriate for many projects (or as a finishing step where a lot of peer review/development has already taken place in the wiki).
