Another version of NXT Bluetooth API is available here:
For now, the package name is icommand as I'm not sure if this will eventually be part of leJOS NXT or reside on its own. This version contains classes for directly accessing sensors, motors and a few other things in an easy way that is similar to leJOS:

This release also has some package names and a jar, and some Java docs which can also be viewed here:
As always, comments and suggestions are welcome.
