At PDA247 I came aware today that Stéphane Magnenat offers a Perl script for download
which is supposed to automatically convert the Wikipedia SQL database to Plucker files.
Google revealed more interesting links to Wikipedia conversion tools:
Wiki2Zaurus - Wikipedia for the Zaurus
With those tools, it should be easy to convert the database to any reader format that supports large files (e.g. iSilo). I'll give it a try tonight.
