I'd be glad to help contributing the guessing machine implemented in
FriCAS.  (described in detail in 


meanwhile published in Journal of Symbolic Computation.)

It has efficient pre-made guessers for:

    linear and nonlinear recurrences
    (analogous to the linear case covered by GFUN)
    linear and nonlinear differential equations
    (analogous to the linear case covered by GFUN)
    nested products and sums of rational functions
    (analogous to the case of products covered by rate)
    functional equations
    (yielding a polynomial p such that p(f(x), f(x^2), ..., f(x^n))=0
    where f is the generating function of the given terms)
    algebraic dependencies between a list of sequences

    q-analogues whenever applicable

please let me or fricas-devel <fricas-devel at googlegroups.com> know if
you need assistance.  It is enough to install fricas, no extra packages
are required.
