@JC: I've been meaning to play Integration: The Stranded Light, though the LAME and RBP requirements always made me shy away from it though. Does RBP work well with the changes that OOO introduces?
I've used RBP with Vanilla, TIE, OOO, and OOO+MMM, It's worked fine for me and melded nicely with all of them. bg himself uses FCOM so of course it gets along fine with that too. There's even a FCOMadditions
optional plugin in RBP that requires OOO+MMM and adds a few of the new races to the leveled listso you might occasionally come across them when fighting conjurers, marauders, etc.
Let's see what else is there? (tag searching http://www.tesnexus.com/downloads/tags/search.php" and sorting them by downloads-desc:

And those are just the first 10 pages, there's 80 more... I kind of selected mods randomly from there avoiding simple graphical stuff and gameplay things because that's more of a taste type thing than a simple "it's either lore friendly or it's not lore friendly" thing.
