Hi, in Milan, we did a CP-based column generation too, but using the  
Gnu Linear Programming Kit (GLPK) instead of the lp_solve.

As long as you use a C/C++ library, it should be "easy" to develop a  
hybrid CP/MILP solver.

We have in plan to experiment with Gecode other hybrid CP/OR  
techniques as well.
