According to the OOOWiki, Andre appears to be working on this so I reassigned
the issue to him. The current status is this:

-IBM has some ownership over the COIN-OR code so Rob is trying to see if we can
get some improvement on the license. This will probably take some time still.

- I was asked by a COIN-OR guy in private about the chosen library: "It is just
a wrapper around OSI and does have a couple of bugs in it too."

So we should probably check OSI, which is a general interface for many solvers.

BTW, the author of the proof of concept mentioned:

"In addition to Clp, the Cbc project is needed for the integer 
constraints that the existing, lp_solve-based component supports."
