This lists lots (all) of the Wikis: http://www.c2.com/cgi/wiki?WikiEngines
Use Emacs for editting! http://zwiki.org/EmacsAndWiki
That whole WebLog thing...?
SpamBot detection, freezing out users that pull too many pages too quickly (worth it? Worth anything? I'd want Google to be able to go through the pages)
Inline inclusion of other wiki pages
There's a ton of possible widgets: Twiki plugins
IE allows WYSIWYG HTML editing. Some comments My WebOS had some stuff along these lines, perhaps (they are now gone -- links to archive.org of them) MS Wiki also does this.
Open Wiki might be of interest in terms of XML backend and diffs.
RSS feeds. I'm not sold on making the Wiki the central metaphor for everything... WebLogs and external feeds might be overdoing it.
InterWiki (or inter-site) linking: http://openwiki.com/ow.asp?InterWiki -- I think this does kind of belong, since linking is central to Wiki-ness.
BreadCrumbs of some sort...? Not being naturally hierarchical, this is subtle. Base it on navigation (I believe OpenWiki might), or annotated (like TWiki).
Attachments? I have better ideas with hierarchical Wikis... (i.e., non-HTML/XML pages, and a page can become a SubWiki)
Nice diffing, like: http://openwiki.com/ow.asp?p=OpenWiki&a=diff&difffrom=146
Branches in versioning (?): http://openwiki.com/ow.asp?p=OpenWiki&a=changes
RDF -- totally right for Wiki. Special Wiki RDF extensions: http://www.usemod.com/cgi-bin/mb.pl?ModWiki -- somehow related to RSS?
Page aliases -- e.g., for plural versions of a term.
UseModWiki has some stuff with subpages.
Automatically notice homonyms, e.g. GroupNameReuse, ReuseGroupName: StrikiWiki The whole wiki interface weirds me out. But maybe that means there something novel there...? Actually, it just seems to have a wacked-out interface (hint: hit the arrows, not the heading words), potentially a rich navigation (if it was more intuitive)
Manila might have some interesting ideas -- more CMSish. Ditto PARC's Sparrow
SWiki is a popular branch of Wikiness... still trying to find what's novel about it... maybe not a lot. But they're working on it...?
AtisWiki allows multiple formats for input. But it's kind of gone -- very early offshoot of WikiWiki.
ZWiki's remote URLs kind of elegant: http://zwiki.org/RemoteWikiLinks
http://tavi.sourceforge.net/ -- I think it is actually expanding the textarea width to my screen?

I would like to see a CMS that handles standard HTML documents or at least standard HTML document bodies. I could use this in a couple projects, although none that's urgent to start right away. The thing is, when ppl already know HTML, or you're dealing with outside authors that have already written an HTML article, it's easier to use that as your source rather than insisting on some "pure" XML or wiki format. Yes, it causes complications for converting the article body to another format later... IF that ever becomes an issue for the particular application. Maybe it won't.
A flexible CMS with a configuration option to accept only HTML format, or only wiki format, or the author's choice, or both in one document, would be the best.
It would also help to have an option of "accept the source format without conversion and serve it as is without touching its internal structure" alongside "convert the source document to an in-between format so it's easy to reconvert into any output format."
