Disable "show password" in Keychain Access Is this possible?

I know some users use this function to recover forgotten passwords, however revealing a password in plaintext feels like extremely bad practice.

In my case, multiple users share a workstation, and all have the admin password. Keychain stores passwords to my personal accounts that we do not share. My password is sitting there waiting to be ripped off.
The keychain is an encrypted container and only the user who has the password can unlock it.  Being an admin on a computer does not allow you to unlock the keychain.  Not even root can do it.  

Of course, as an admin, there are ways to install software and get the data but it isn't as simple as opening the keychain and looking.
