(BTW, EPD is free for academics.) I eventually decided to keep supporting 2.5, and just have reduced functionality for module-tasting on 2.5. (Specifically, tasting zipimported modules doesn't work completely well on 2.5.) Maybe in a year or so I will finally kill Python 2.5 completely. Thanks everyone for your advice! Ram.
