[wp-hackers] Filtering Themes visible for a particular network

[Shelby, Harper]

I've been asked to implement theme filtering for a multi-network installation, so that network admins only see those themes which "belong" to them. In the existing installation (on MU 2.9.2), this was done by altering wpmu-themes to check for a Tags value in the theme's CSS file and filtering based on that. I'm trying to move this implementation into a plugin to reduce changes to the core code. Digging into the code, I don't see any action or filter hooks being called in ms-themes.php, so I suspect my best course of action is to move themes into network-specific subdirectories of wp-content/themes, then alter the include path in an admin_init hook to bring in the proper theme directory. Is there a better way to implement this, or are there any potential risks that I haven't seen in this course of action?

Thanks,

Harper Shelby
