If you just need ripples in the water then you could simulate a water's surface with the Phizix extension using many rectangles with joints inbetween them. If you take a look at the included examples of bridges, they act sort of like waves. If you were to make the links smaller and add more joints it might look convincing.
except it'd lag like hell :VQuote:

Soft body dynamics (I think liquids belong to this) are very complex if they're supposed to be REAL. Of course, you can't do it that realistic at realtime, but seriously, animation companies like pixar work ages (multiple years) on algorithms for that. I think there are some decent engines for this, but I'm afraid that MMF might be too slow to handle it - Not too sure.
i guess a really crude version could be done in a way similar to the falling sand games, which would give you some ability to have flowing liquids, though it'd take more work getting surface effects to work like real water, and the code would need to be optimized into the ground to keep it from hogging your CPU
