[Apple] Massive Openfirmware password!

[Ryan Marcus]

I am the administrator at my school (sad, huh?) and I was wondering if there was anyway to place an open firmware password on all 800 of our school computers... I have remote desktop access to them all.

Short of writing an AppleScript.

Also, is there anyway to completely disable open firmware until ARD says its ok?

Hmm, I don't think anybody here has any serious Apple experience, but I might be able to help you. 

Would this be considered a "security" thing? I don't want to post it to the wrong place and look like a fool to real people :)
