Domain Access

Utility module that adds new hook_url_alter() hooks for other modules to implement. Also replaces the need for custom_url_rewrite() functions in settings.php. This is a backport implementation of the proposed Drupal 7 patch #320331: Turn custom_url_rewrite_inbound and custom_url_rewrite_outbound into hooks.

If you use any of the following modules, it is highly recommended that you install this module:
FeedBurner
Subdomain
Domain Access
Context Prefix (part of the Context module)
Bandwidth

This module extends Domain Access (DA) functionality to taxonomy objects. It makes taxonomy terms dependent on domain access rules like nodes. In practice, it means that term editing forms are extended by new options for choosing domains where term must be published. This options block is identical to the block for nodes from DA, but have some additional features for allowing inheritance of domain rights to child nodes or terms.

And when you create nodes with term which have assigned domain right, than term right inherits to this new nodes.
