There are several suggestions that, by themselves, are not terribly feasible or interesting, but merging them might lead to something good:
unlimited item duplication (require 2 of the original item, consume massive amounts of UU, but allow you to duplicate just about anything -- perhaps use electrolyzed/charged UU for this).
crafting 1 of anything that can be made with UUM instead of the amount in the solid UUM recipe (rounding in the less-favorable direction where necessary; it's not going to make much difference, though). See also #23.
assembly table/thermionic fabricator recipes, using liquid UU instead of their normal prerequisites. See also #8.
Other carpenter-like recipes, with or without consuming the input items.
UI-wise, I see this as being very much like the carpenter: a liquid tank, a 3x3 crafting grid, and an output slot.
The duplication recipes may end up being also present as accelerator recipes (consuming liquid UUM out of the new machine's tank(s) in the process).
The UUM crafting would require the normal crafting recipe present, but the input solid UUM will not be consumed (only liquid UU out of the tank).
The assembly table recipes would be shapeless (as they are in the assy table itself) and the fabber recipes shaped; the input materials would be consumed.
Some recipes may consume many work cycles and drain liquid UU gradually; in those cases, we want to be certain to keep the progress already made; if possible, we want to lock the crafting slots and provide an "abort" button, allowing us to try to refund some of the UUM used in the process.
Finally, liquid input could be done by attaching ITankContainers to the sides of the machine, with the sides being configurable, like in the liquid electrolyzer. This also suggests several of these carpenter-equivalents could share a liquid pool if they're next to one another; a refinement that may eventually be ported to the accelerators, as well.
