-I need to look at the range of things that other wikis use their plugin systems for, but preprocessor directives as plugins certianly seems useful, even if it's not a complete solution.

+* For PlaceWiki I want to be able to do some custom plugins, including one
+ that links together subpages about the same place created by different
+ users. This seems to call for a plugin that applies to every page w/o any
+ specific marker being used, and pre-or-post-processes the full page
+ content. It also needs to update pages when related pages are added,
+ so it needs to register dependencies pre-emptively between pages,
+ or something. It's possible that this is a special case of backlinks and
+ is best implemented by making backlinks a plugin somehow. --[[Joey]]

+* random page (cgi plugin; how to link to it easily?)
+
+* How about an event calendar. Events could be sub-pages with an embedded
+ code to detail recurrance and/or event date/time
+
+* rcs plugin ([[JeremyReed]] has one he has been using for over a month with over 850 web commits with 13 users with over ten commits each.)
+
+* asciidoc or txt2tags format plugins
+
+ Should be quite easy to write, the otl plugin is a good example of a
+ similar formatter.
+
+* manpage plugin: convert **"ls(1)"** style content into Markdown like **\[ls(1)\]\(http://example.org/man.cgi?name=ls§=1\)** or into HTML directly.
+> With a full installation of groff available, man offers HTML output. Might
+> take some fiddling to make it fit into the ikiwiki templates, and you might
+> or might not want to convert pages in the SEE ALSO as
+> well. --[[JoshTriplett]]
