I was unable to master a new PPC ISO this weekend due to a number of problems. Its not impossible, but very difficult and time consuming with the hardware available (important note: Ubuntu LiveCD does not work on G5s). Instead of the Live CD, I've made available a tar of all the files which are not provided by Ubuntu packages. The download information can be found at http://www.scipy.org/SciPy2006/LiveCD. Bryce
