Ability to have a node / view use a specific theme rather than the default theme

I have created a module that hooks into node edit/create and provides a Node Theme dropdown box for selecting a theme that will always be applied to that node. The selection is then stored in a new table (nodetheme) and used with hook_init to set a custom view for that node.

I haven't gotten around to doing the same for Views, but the functionality is needed there as well.

Here is a link to the code, which is also attached: http://ayendesigns.com/testing/drupal/nodetheme.tar.gz
