multisite settings page, saving data in db – can wp api handle this

I’ve got a multisite install:
I’m looking for wp api to handle a settings page I’ve created to track and config in-house plugins (has its own top level menu link and sub menus)

I’ve used http://ottopress.com/2009/wordpress-settings-api-tutorial/ to take a stab at this, but I feel as though it’s only for single site? Either that or I haven’t set it up properly, but I’ve gone through the whole thing multiple times and there’s no db update or anything.

Originally I had it linked to options.php, but obviously as it’s a network settings page the page was not found. I removed the options.php and let it just post back to the current custom settings page. Will the functions not fire this way? Is that my problem? I’m pretty new to WP and php, so I’m a bit lost here.

Any help would be appreciated.
Thanks!
