I have created a standalone Wikipedia which could become the foundation af a DVD release or a desktop/intranet version of Wikipedia, currently Windows only (but should be easy to adapt to Linux/Mac).
I don't have anywhere to put a DVD image, so you'll have to bake your own. All you need is my software (based on tinyweg and sqlite, running a real, unpatched MediaWiki) [1] (ca. 6MB) and a XML dump of wikipedia (I recommend [2], ca. 762 MB). Download both, uncompress the software (no need to uncompress the XML file!), and follow the instructions in the README file.
Some issues: * The creation of the package takes time (think "over night") and disk space (~2.5GB) * Page rendering is a little slow, but bearable, roughly depending on the number of links on a page * No images * It doesn't run directly from DVD, as tinyweb insists on writing log files; you'll have to keep the whole thing on hard disk
Things that don't work but which should be easy to do (for someone with time on their hands) * Interwiki links are renderd as "red links" (should be fixable in LocalSettings.php) * Search doesn't work (should be fixable by patching MediaWiki, at least for title search)
Technical note: The conversion software (GPL, but source not yet included - too messy) generates a sqlite database with everything BUT the page texts. These are copied into a single large text file, and the database additionally stores the position of the respective text. That turns out to be the fastest way to query the database. I tried reading from a compressed text file, but the performance was horrible as there's no way to directly seek a position in a compressed file.
