I'm definitely interested! :-) Alas, I have no time at all for this....

Matthieu, if you need something now, try Mozart (www.mozart-oz.org) with 
the XRI module (http://home.gna.org/xrilpoz/). Note however that there 
are no edge-finding propagators for the continuous-domain variables in 
XRI. There are also a few minor bugs in XRI, but it's all listed in the 
mailing list and there are workarounds.

By the way, I've heard somewhere that the AVISPA group, the authors of 
XRI, work on integration of Mozart and GECODE. So maybe there will be a 
version of XRI for GECODE someday? (Or someone does this "from scratch" 
- XRI is in fact a rather thin wrapper around the smath library.)

One more question: how do you plan to employ AC|DC2?

Cheers,
Filip
