Hi, Anthony. I can't talk about this topic myself, but as it is in the list of idea is listed on the GSoC ideas list, then it is a good task. Regarding difficulty, I only add that the problems may be how to embed it in the SymPy core. It can be easy to implement as a separated program, but in SymPy the implementation must have effective caching, is related with interaction with the core, inheritances from main classes, embedding to the printing system, assumption system, maintain various bases of polynomials and so on. Practically the most of efforts for implementation are directed to solve those problems. Not also, that some work was started in the master brunch (as mention i Idea page, take a look at sympy/polys/factortools.py in the SymPy source code), and also at the PR 609 [1]. May be they are only about the multivariate polynomials themselves, without factorization problems. I hope that others can clarify more about current status. Meanwhile you can go ahead with this topic, see the [2] and try to send a patch.
