Automated/Scripted Unity Internet Activation

I have a bit of a problem:

I need to install and activate Unity Pro on 60+ academic lab machines. I have all the necessary license keys, but haven’t been able to find a good way to apply them to the machines. Having to activate each and every machine by hand whenever I reimage the labs is rather absurd and impractical, as is maintaining 60+ 100GB images.

Is there a way to do activate Unity on a machine using the command line? Or some other way to quickly and easily activate Unity on a machine quickly and easily without direct interaction? If it works for the free version of Unity as well, even better.

Guess there is no way to do it from 2010 to 2012.
