First, what a smashing component guyz !
But what I really don't understand is why you cannot link items with jce link explorer or linkr... You cannot browse the k2 items but only joomla articles. And it's too boring for clients to insert the absolute url... I think it's an essential feature (compatibility with joomla plugins) for k2 to become a CCK useful. One question : when do you plan to release plugins for K2 ?

If you're using JCE as the editor try the following community.getk2.org/forum/topics/at-last-a-working-jce-advanced
