future of LiveUser

Hi, I would like to start a small thread to think about some steps to go on with LiveUser developement. Are there any active LU developers listening to this list? ;-) My basic idea is to move to PHP 5 and the second is to support some of the "modern" ORMs like Doctrine and Propel. I also think we have to change the way the filter works. Imagine if you use Propel or Doctrine these nice packages have their own built in filter magic. We should do a further split with the admin package and move the storage containers into separate packages with some separate features. Any ideas how / why / what could be improved? I guess the biggest question is whether one should do a major change in the existing packages or to start with a LiveUser2 branch? IMHO we should start with LiveUser2 and do a bit of nice PHP 5 refactoring!? Regards, Matthias
