I did install and configure ls2, and it looks a lot cleaner, congrats!
Also the code is very well structured.. of course, cake helps! I see there is need to upgrade to cake 1.2 final (now it's on rc1)
But there is a long way to go until all the 1.8 features will be implemented.
I will look for a roadmap (?: http://docs.limesurvey.org/LimeSurvey+2.0+Roadmap doesn't work)
Mainly all the export features, groups, question routing :)
And as far as what I need from ls, a better, more detailed front-end (or front-end APIs) would be great.
