Oh heck yes.

Relief. stringing problem 100% solved by using Slic3r, a new gcode generation program. It's also about 5x faster and generates gcode that prints faster, and is far easier to configure even than SFACT, which is far easier to configure than Skeinforge.

There's still some unevenness in vertical surfaces, probably caused by slightly low flow rate (I could have overstated the filament diameter, for instance) or perhaps the hotend temperature was a bit high. I'll work on that.
