Hey, I know there's a bunch of wiki questions already but I was wondering if anyone could recommend a good wiki thats good for use internally and can be access by some clients?
Must be free (F/OSS preferred), Ubuntu (9.10+) compatible, and have per-page permissions.
I setup MediaWiki and its fine for internal use but I don't know how, without some severe hackery, how to restrict a client to just view one page and all the images on it and css. It'll be worse when they ask to be able to modify it as well.
Edit: also, please no java solutions
