as we get many separate inquiries concerning the licensing of our Likno AllWebMenus WordPress menu plugin, please allow me to clarify this here.
Our WordPress menu plugin is currently offered for unlimited domains (websites). It used to have a per-domain licensing, but this is now changed and it is for unlimited websites (WordPress or not), provided that you own 1 license of AllWebMenus Pro.
The current "Unlimited API domains" license means that you can create database-driven/programmable menus, or advanced WordPress menus, Joomla menus, Drupal menus etc. for as many websites as you wish, without any constraints on domains, submenu levels, behavior, design or content.
Our latest plugin version (1.0.20) also supports the new WordPress 3+ feature of "Menus".
You can use the "menu structure" of your own WordPress "Menus" (version 3+ only) on AllWebMenus themes automatically (dynamically) and show nice-looking menus on your blogs.
If you have further inquiries about the plugin's licensing or its functionality, please post them here so that other WordPress users can also get access to these clarifications.
