There is no confirmed working Conax hack in the public domain yet, so the answer to your first question is: no. But smart money is it will happen soon and I for one have already bought my Conax CAM before it does and the price rockets.
For channel details, see (as ever) either satcodx or lyngsat. EG http://www.lyngsat.com/dig/canaldigital.shtml There's a lot of Conax at Intel707 (0.8w) & Thor (1w). All the usual stuff: Discovery, Sport, Films, etc. The commercial pirates selling the commercial Conax pirate cards refer to this as the "dream package".
