The overall architecture of this extension is more or less complete. However we're stuck with the MIME handling mechanism in Mediawiki. Since CBZ, ZBR, etc archives are also regular compressed archives, having Mediawiki hand the handling of the CBx archives to the extension rather any other handlers is problematic. If you're interested in this wiki and have ideas on how to proceed, we\d love to hear form you.
