Pydev should be able to be run using Python 3.0. There seems to be a handfull of changes that look pretty typical if the conversion from python 2 to 3. I have already done some of them so that I could use it pydev, and I will will offer the changes to you it if you ask, but I am not sure they are done in a way that you would want them done. A real quick and dirty lets get this working. Also, when you add Python 2.6 of 3.0 in Preferences Python Interpreter, it appears to select the wrong set of defaults and you have to set several by hand and maybe even add some missing one. I don't believe that I could be the first person to bring this up!
