Educational Versions work with CAM / CNC?

.
I'm taking a CAD class thru a local community college. As part of the class, I'm getting a three year license for both AutoCAD 2012 and Inventor. I have seen that I can also purchase a "perpetual" license for this software from places like Academic Superstore, ect.
.
I know about the limits on commercial usage of these programs, as well as the "watermarks" that print on any paper output.
.
My question is if I can use these versions with a homemade CNC system?
.
Thanks!!

Downloaded the MeshCAM trial. . . works great. . .

The education versions of Inventor can export DXF and STL files which can be imported into 2D or 3D CAM programs. I've done it, it works fine.
