http://forum.industrial-craft.net/index.php?page=Thread&threadID=8269 It's a really cool mod that allows for more use with UUM, and since most of the UUM recipes are disabled, I thought it would be nice to have. Basically it gives UUM the ability to be turned into it's liquid counterpart. It currently doesn't have too many uses. But the things it can do right now is, Duplicate liquids using the Buildcraft refinery at the cost of uum. And the accelerator, it instantly does the action of the machine it's connected to, again; costing UUM. (really good for AE autocrafting) Most of the things it adds are configurable, so it has a lot of customization in terms of the numbers on the IC2 forums thread.
I was going to suggest this mod as well. The instant crafting for ME Networks would be amazing. And for the cost of UUM it balances really well. I would be a little worried about duplicating some liquids for the same reasons that all UUM ore recipes are disabled. Here is the add-on's LiquidUU Conversion Ratios and Rationale
I'm not sure but I think I remember pyro testing this and it was buggy as. Maybe wrong and they have improved it. But the idea is nice.
Liquid XP sounds OP..? Could be fun to experiment with though... Liquid UU just seems to make sense some how.
I did test it a little bit the only problem I see is automation of enchant book production but that's a discussion for another thread as for this I will look into it once I have went over the mods for updates
