Buckets for all IC2 liquids.
this would also be great for mod compatability, because cells sometimes don't work with other mods liquid inventories.

Universal fluid cells already have a same functional. Described problem is obviously an "other mods" side problem, because minecraft forge have so-called "fluid container registry". You can handle any fluid containers via it with easy. In other side to handle buckets you need to use ASM "event handler" which is already used in BuildCraft. Using it two or more times could produce unpredictable result.
