Open Inventor for Windows

First let me apologize for posting this here, as it should probably be in the high level APIs board, but it seems as if that board hasn’t been touched in a long time.

I would like to get OpenInventor running on a windows machine. SGI released the library opensource for IRIX/linux, and a port to windows can be found at: http://www.cg.tuwien.ac.at/hostings/openinventor/

The problem is that this particular port uses the Qt library for windowing functions (using the SoQt bindings). Since Qt for windows is not public (it costs $$$), I would rather not use this. Has anyone gotten OpenInventor running uder windows without purchasing anything??

Thanks
Mark

PS - This will be used by students in a university class if that affects any costs involved.
