LISP to detect if Drawing is "infected" with Educational Version

[BlueVue]

Is there a way for LISP to detect if the current drawing is from an Educational Version??

We've discovered a few drawings at our office that have been infected, and we'd like to prevent it from happening again. We have a company-wide ACADDOC.LSP routine that does some stuff for us, and I'd love to be able to have that LISP check any opened file, and if it's tainted, have it pop up all kinds of alerts and warnings, and force the drawing closed without saving.

Is this possible?

There is a free 3rd party solution available if you are interested.

Look for EDUSCAN.ZIP at http://www.dotsoft.com/freestuff.htm

Also, recent versions of AutoCAD and verticals (2009 and later?) have a built in warning when an EDU drawing is opened.
