I'm not familiar with the internals of FLIP fluids so I wonder why it is 
difficult to spawn them on a plane (which can be done with regular 
particles in Blender for example)?

I'd also like to add that I would appreciate if the inflow feature would 
be designed in a way that it can be expanded in the future. One thing 
you can do in Houdini that is really cool is that you can use a texture 
or a force field to define initial velocity (or mix that influence in). 
That can be used to for example add that extra tidbit of realism to the 
simulation of a water faucet.

Cheers,
Gottfried
