Here we discuss the key aspects of a practical implementation of such approach and demonstrate how one can overcome the main technical problems: Gauss constraint violation and reflections at the boundaries.LaTeX [PoS.cls included], 6 pages, 1 figure, talk presented at Lattice 2005 (Topology and Confinement), Trinity College, Dublin, July 25-30, 2005High Energy Physics - Latticetext
