Let me just mention that \input@path is an interal macro and not a public one available to authors in order to be redefined or extended -- \graphicspath is a different beast. > Is it possible to parse the document for such (re)definitions, and > provide additional paths to ffap-latex-mode via some defadvice? Or is > this too complicated to do robustly? ffap.el is an Emacs core library; I suggest you ask Emacs maintainers about this addition. If they agree, this can also be useful for people who use the builtin LaTeX-mode. Reg. usefulness: I'm not sure if I would agree if I was in charge. epslatex.pdf has a section about this kind of additions (13 Using Subdirectories). Maybe the reasons given there don't apply to modern TeX installations and computers anymore, but in general, supporting non-public commands inside an editor is asking for trouble (IMHO) and using Kpathsea is much more reliable.
