Editing themes without access to filesystem

Hello,

I need to edit themes in browser.

I found two modules:
- Theme Editor - http://drupal.org/project/theme_editor
- Thematous - http://drupal.org/project/thematous

But no one of these is usable for me. Theme editor is not yet ported to Drupal 5 and Thematous is using PHPTAL template engine (I want PHPTemplate).

Anyone knows about some working solution?

Thanks.
