Custom Adsense Plugin

I can’t trust those adsense plugins from wordpress plugin directory, because I fear sneaky codes that may switch back and forth the adsense code to give the original creator the adsense impressions that I may not approve of. Therefore, can developers here thinking about developing an adsense plugin that will allow all members of WordPress 3.0’s with multisite enabled using Buddypress to be able to activate adsense plugin on case by case — with that I mean each user of a site can activate plugin or choose not to at their own discretion. The plugin should allow users to enter their adsense code or adsense ID.

Why? WordPress 3.0 stripped javascript code away, and additional tags plugin is too broad which may cause security issue. Just need a specific adsense plugin that will not cause security related problems. Thanks!
