I've published the oldy  "ODE trimesh collision"
OPCODE version . So you can do all necessary tests and
benchmarking with GIMPACT and OPCODE; also you can 
improving the ODE-OPCODE package if tou want.
- Download the updated gammaleon demos:
 It has the last demo written with the previous ODE
using OPCODE. 

And download the older version of my modification of
the ODE library working with OPCODE :
Good luck.

PD: I don't recommend forcing ODE to supporting both  
 engines (GIMPACT and OPCODE). It could complicate the
integration of ODE to other projects, which can be
frustating for newbies and unskilled users.
