convex support

Does anyone know if the convex support is usable?
i have a scenario in which i need to have about 100 convex objects interacting togheter, if some knows details about this feature pls explain it shortly
Thanks!

it's a WIP but some are usable. Check tests coming with ODE and you see how it works.
Sadly it use a bad format (planes list + vertices list), and doesn't accept a vertices + indices list...
