The framework and released plugins currently rely heavily on mootools, which unfortunately tends to conflict with jQuery. There is a "no conflict" script for jQuery that is built into the framework as well, but that doesn't have a 100% guarantee to not have problems.
There is active development of a jQuery conversion for the framework javascript, but I'm not the one working on it, so I can't really give any idea as to when it will be done. I can only guarantee that as soon as I can stop using mootools I will be thrilled to do so.
As for alternates:
