I've spoken with folx at Linterweb, who maintain a deposit of
zeno-formatted[1] dumps at
http://www.okawix.com/zenos/
Files ending in .okawix are tar files.
They plan to increase the frequency, and are moving FR, DE, EN, ES, and
PT to another server for particular support.

[1] Zeno format information I've only been able to find in German at
http://www.openzim.org/Zeno_File_Format and
http://www.digitale-bibliothek.de/scripts/ts.dll?s=1&id=57107E74&mp…dsLM=/sel/2/.
