I have been waiting for the new 10.4 versions to come out and I just couldn't wait anymore, so I decided to try out a Bitnami virtual appliance. Let me tell you it was not worth it and it made me appreciate what TKL does even more! I posted about my Bitnami experience here: http://www.danielrobertson.info/2010/05/bitnami-redmine-appliance/
Any news when we can expect the new betas to be out? Can we get a copy of the core sooner, or are you working on them all at once? I don't intend to be pushy, just eager.
