If you think Firefly is going at a snail's pace now, just try adding GI, and it will be several orders of magnitude slower, unless you vitiate the GI settings to the point where they're almost useless. So my vote is to leave Poser as Larry W. originally intended it: an artists' aid, not a modeller/renderer. What I'd like, instead of GI, is for them to fix the joints so we don't get those awful bending problems by default in the knees, hips, elbows, shoulders etc. If they need to jack the price up another $199 or so to do that, so let it be done.
