Interesting, I might start looking into noncommutative algebra soon, so it is 
interesting to know that there is a variety of code out there.

Does it compute a Gröbner basis (AFAIK: no)? Does it allow to do a reduction 
modulo an ideal basis (e.g. if I know I have a Gröbner basis)? LCM, GCD? As 
opposed to adding and multiplying.

Sorry for replying so late, I am going through my mail just now.
