Empty roots in node hierarchy

Hello,

Sometimes it would be good to have node that has nothing but child nodes.
E.g. Node 'About Us' that contains nothing but should be automatically redirect to node 'History' or 'First persons of company'.
I've decided to make a module, that implements such node types.
The only thing, it does is - on hook_view() check, if we show standalone page and there is a child below us - do drupal_goto() to first child. Otherwise show default text.

In attachment you may find archive with this module.
I'm not sure, if this module should be done as separated module. I do not see any objections to either put this module as submodule of Node Hierarchy, or even include code from it into the NH main module code.
And thanks to your module.
