Part of contact filtering is to sum up close to coincident constraints 
into a single constraint, for example using the average of the normal 
and penetration depth. If you get into situations where you get lots of 
contacts, filtering is very necessary.

I guess it'd be useful if ODE had a built-in "default" contact filter 
which could be used by people who don't want to write their own.
