At the beginning of 2007, I forked Instiki 0.11, and started to develop this MathML-enabled branch. Two years later, we decided to merge the two branches. If you’re running Instiki 0.16.3 or later, you’re actually running this branch, and the information here pertains to you.
Math support is based on itex2MML and is enabled if you choose the (default) “Markdown+itex2MML” text filter. There’s a quite serviceable LaTeX export (click on the “TeX” link at the bottom of any wiki page).
Since this version of Instiki emits real XHTML, you can also do fancy things, like embed inline SVG. It should render in any SVG-capable browser.
You can have multiple wikis (“Webs” in the parlance of Instiki) under the same Instiki instance. Each wiki can be password-protected (with its own distinct password). And, if you’re so-inclined, you can publish a “read-only” version of a password-protected wiki, so that others can read, but not modify, what you’ve written.
Installation is very easy. Instiki comes bundled with its own webserver (which, by default, listens on port 2500), so you should be up-and-running in minutes.
Of course, there are always improvements that can be made. That’s where (I hope) you come in …
The main motivation for this branch is its support of math and inline SVG. Other features include
application/xhtml+xmlto compatible browsers. That includes Internet Explorer, with the MathPlayer plugin installed.

Instiki is free software, licensed under the same license as Ruby. The current release version is 0.20.1. The current development version (which is what this site is running on) is available from the BZR repository or as a tarball. The BZR Repository has an Atom feed, with which you can stay abreast of the development of this software.
Math support is provided by itex2MML Ruby bindings (available as a rubygem), whose development can be followed by subscribing to its Atom feed. itex2MML is licensed under a triple LGPL, GPL and MPL license.
Here’s a comprehensive list of the changes made to this branch of Instiki.
