Hiding uid 1

OK, I have searched and searched...I can't find an answer, but may have to make a module cuz I can't be the first to need this.

I am starting a multisite setup offering to support others' sites/domains...when I set them up, I set them up with a default uid 1 for me and my business partner to use for support reasons...in user management of all the sites, I want to hide uid 1 from the user list, edit form and such UNLESS you are logged in currently as uid 1...there must be an existing module, patch or something to support this, mustn't there?

Thanks for any help.
