RE: Up vector on particles flowing on a path
There is also emtools from Eric Mootz that contains a compound for driving particle orientation with lots of options. IIRC called Align Orientation or similar.

The align on velocity in the flow on path node overrides anything else. I want them to align on velocity/direction but also stand straight up pointing at Y. Kris -- Softimage Mailing List.

Re: Up vector on particles flowing on a path
A few cross products: direction vector x global Y axis = binormal binormal x direction = your desired up vector order is important. Also normalize the resulting vector to be a unit vector to make other downstream operations predictable.
