This isn't about commercial *use* -- non-commercial users can and do use
commercial tools.
I'd hope your research group can find the budget to license the appropriate
quality of tool (software or otherwise) for your work. Free software is
great, especially when you want to modify it (e.g. Maxima), but what's the
problem with using a proprietary Lisp implementation if it works better
than free ones? Surely your research institute uses proprietary books
(copyright by author), commercial instruments (covered by patents), etc.
