wordpress mu help needed

Here is the deal. I am trying to get a blog hosting site set up with wordpress mu. I would like to have plugins installed for adsense/affiliate programs and keep others from having access to the plugins. The plugins do not show up in the wordpress mu plug ins folder and only show up in the wordpress plugins folder where everyone has access. Any ideas on how to add the plugins with out giving everyone access to them?

This issue is bugging the crap out of me and any help will be greatly appreciated.

found it, just download wordpress commander and upload in to your wordpress mu plugins folder. from there you have complete control over all plugins installed in the plugins folder.
