If you do set up a multispectral system, please make it flexible to allow
for synthetic multispectrum rendering from games. I've long wanted to write
a game that did multispectral rendering that involved such things as
visualizing magnetic and magic fields (with appropriate user filters), but
I've yet to see a multispectral system flexible enough, and I've never had
the time to write my own.

Just a suggestion :-)
