This is good that people are picking up from where I had to leave off.
The IuB mod was a bit complicated though so make sure when integrating something that it's not overwriting some earlier change - most of what I did is in the readme file, but not necessarily all.
Theres also some other tweaks I'd make in retrospect - for example, resizing the size of the particle textures (halving them, say), in order to improve performance.
Anyway, keep up the good work!
