  The reorientational nonlinearity of nematic liquid crystals enables a
self-localized spatial soliton and its waveguide to be deflected or destroyed
by a control beam propagating across the cell. We demonstrate a simple
all-optical readdressing scheme by exploiting the lens-like perturbation
induced by an external beam on both a nematicon and a co-polarized guided
signal of different wavelength. Angular steering as large as 2.2 degrees was
obtained for control powers as low as 32mW in the near infrared.
