I'd advise you not to get your hopes up. Considering the many subtleties that JKII will incorporate now with increased saber tactics/maneuvers, I don't feel that 56k would be able to handle that, and give you a fair response in return. A delay of half a second could shift the balance in a saber fight, it seems.
I could be wrong, but I never had much luck with 56k, unless the server I was on had very few people on, and this is across Q3/RtCW. Pings usually were around 260. Not _really_ bad, but I'm of the opinion that you'd need a much lower ping to increase your chances in the deadly dance of saber-play that will soon take shape on the JKII servers...
