One-time passwords

Hello!
Can you meke an an option to create one-time passwords?
I can make it, send to someone, and it will be blocked after the first use.
Please!

This can't be done by a single magic option, unless we find a way to allow all the instances of the installer communicate by telepathy.

What you want to do is an online activation, i.e. the installer asks your server if the serial can be used and if so installs the program and notifies the server the serial has been used.

This can be done with custom plugins, but not in this version of ICP.
