Thanks for your info.  I appreciate any and all opinions you can give.
Assuming for a minute that students will need just basic
calculus, basic algebra and basic arithmetic,
Maxima is ready NOW for this market right??? 

Probably the most complicated equation students will ever work
with is some polynomial or fraction with trig functions.
I assume the integration, ODE and plotting engines for THESE
guys was perfected in GPL'd Maxima years ago right???
