[ODE] "synchronous" ray intersection tests?

Sure. You can implement that very function, by having it call
dCollide between a "utility" ray that you create at start-up, and change 
using the parameters given for each query, and the geometry of the 
world. Capture the results in a static variable (or send in a 
pointer-to-result-storage) in a specially formulated near-callback function.

Btw: CarWorld does this all over the place :-)
