Well, the installers don't seem to work very well on OS X (at least on the public beta) so the easiest thing to do is just grab the .jar file from http://ftp1.sourceforge.net/jempeg/jempeg-1.0b1.jar and save it to your home directory. Then open a terminal window and type...> java -cp jempeg-1.0b1.jar org.jempeg.empeg.emplode.MainThis should actually work on any unix with a recent JVM. Also, autodiscover does not seem to work properly so you will have to specify the Empegs IP address with the options button in jempegs connect dialog.-Mike
