Is it a lot of work to add access to the prismatic joint within the box2d code?
I was looking into making a custom behaviour for it then noticed the code is in the runtime.js. <img src="smileys/smiley17.gif" border="0" align="middle" />
It'd be really useful for making stuff like sprung suspension, or creating a physics version of the pin behaviour.
