I was planning on using IPBM inplace of NewBB as I felt the features offered by IPBM outweighed the disadvantages of having an unclear upgrade path, and the fact that it took a bit more to administer as it wasn't XOOPS core as NewBB is.
However, now that I see Catz is putting his skills into developing NewBB, I think I'll be sticking to NewBB. I doubt NewBB will ever have a feature set as rich as IPBM, but that also has it's advantages in that it's easy to administer.
