We’re releasing AdSense-Deluxe2 plugin that we are using here on Blogetery for revenue share. Originally this WordPress plugin was developed by acmetech.com. AdSense-Deluxe2 is a WordPress plugin offering advanced options for managing the automatic insertion of Google AdSense to your WordPress posts.

Features:

• New: Added revenue share functionality for WPMU.
• New: Added Ads Auto-Embedding: if you haven’t add <!–adsnese–> code into your post plugin automatically will add this code into position you choose.
• Fixed: WYSIWYG drop-down menu (working with WordPress 2.3.3)

Installation: Download the tgz file, extract it and upload the adsense_deluxe folder to your plugins or mu-plugin directory.

WPMU revenue share configuration: To enable revenue share set up following variables in adsense_deluxe.php:

• $__ACMETECH_REV_SHARE - % of revenue share
• $__ACMETECH_CLIENT_ID__ - AdSense Publisher ID must be the same as in $__ACMETECH_AD_DEFAULT_CODE__
• $__ACMETECH_AD_DEFAULT_CODE__ - AdSense code for revenue share

Seems like The WordPress.com Stats Plugin not working on WPMU :(. It has been replaced by FireStats plugin. You can enable FireStats plugin from Plugins page and access stats page from Dashboard -> FireStats.
