[ODE] get acceleration?

[Jon Watte]

Acceleration is the same as delta-v, which is the same as 
force applied times timestep. If you get all the feedback 
forces from all the joints affecting a body, you should be 
able to get the total force, and total torque, applied to 
a body in a time step. I haven't used the feedback stuff 
myself, so I don't know how much of it's already working 
the way you need, and how much you may need to dive into 
the code to expose the numbers.

Cheers,

is there a built-in way to get at the acceleration on a body?
or am i going to have to sniff the linear velocity every frame
and compute it myself?

i'm working with a system which sends position data to client
machines every 20th step or so. what i want to do is send an
"extra" message for any collision which causes the acceleration
to change beyond a certain threshold. thoughts?
