I'm not aware of such a project but it has been on my mind for some time as well. I think this would be a great thing to try; I also plan to add simple support for biasing only root node or nodes that already have large number of visits, exactly to support expensive evaluation functions - I guess it would be useful for this as well. Asking GnuGo for evaluation of all moves would be awfully expensive, I think. I'm not sure if MCTS ManyFaces uses the old evaluation function only for top moves, it would be great to share other information like LD and semeai critical moves; perhaps GNUGo even provides interface to get these as well. Obviously this is not what GG was designed for and will do loads of overhead but could be interesting. I would have tried I but I could not get Pachi to compile under Cygwin and currently I do not a linux machine. Also Fuego had some problems building under cygwin -and has steeper learning curve. Also it would slow under cygwin. At least Pachi multicore due to threading. I'm sorry, I cannot help much with making Pachi work on Cygwin work as I'm only very little familiar with Windows or Cygwin - but if you get it to work (please send a patch if any changes are required!), I can help you out with troubles you would encounter from there on. Not too long ago, Ben Lambrechts has been able to compile Pachi on Cygwin, perhaps he could share some tips? But maybe something changed in Pachi in the meantime that broke the Cygwin build...

Re: [computer-go] Pachi/fuego GnuGo hybrid
The SlugGo team is working towards a Fuego/GG hybrid. But just as our cluster distributed GG added a few new evaluation functions, we are working on an additional evaluation module for Fuego. Work had been slow, but we intend complete the addition to Fuego prior to integrating that into the existing GG based SlugGo code. I agree that Fuego has a steep learning curve, but I also think it is well worth the effort. The basic architecture of SlugGo was designed to be a multi-brain approach, but when we started GG was the only open source engine available, and we always thought it best to build from an existing Go engine rather than develop our own from scratch.
