  Large liquid-scintillator-based detectors have proven to be exceptionally
effective for low energy neutrino measurements due to their good energy
resolution and scalability to large volumes. The addition of directional
information using Cherenkov light and fast timing would enhance the scientific
reach of these detectors, especially for searches for neutrino-less double-beta
decay. In this paper, we develop a technique for extracting particle direction
using the difference in arrival times for Cherenkov and scintillation light,
and evaluate several detector advances in timing, photodetector spectral
response, and scintillator emission spectra that could be used to make
direction reconstruction a reality in a kiloton-scale detector.
