[ODE] Fixed joint no good idea?

[david@csworkbench.com]

Perhaps what you are looking for is actually a 2-step process.

1) disable body
2) detach body and geom by setting the geom's body to 0.

Then stuff will collide against the static geom as if it had infinite
mass, and the body will never have a contact joint added to it, since it
has no geom attached to it.  And you don't have to re-create the geom or
body, just set the geom back to the body and re-enable it and you're off.

Hope that helps,
David
