rational functions over Z/p

I wonder if there is a way of making Mathematica (or Maple) work
with rational functions (in several variables) over the field Z/p of
integers modulo p?
Basically, I need it to be able to do arithmetic operations with, and
simplify on
the fly. In maple, commands such as mod 2 work on polynomials, but not
reliably on rational functions (e.g., can produce 2's in the numerator
or
denominator, or not simplify where possible). I was not able to make
modulus ->
work at all with polynomials (let alone rational functions) in
mathematica.
