Hey hey,
simply inverting the phase, shifting it by 180 degrees, only requires a negative volume. Whereever you can set the volume in percent or have a fixed point of silence, you can do it. Simple LADSPA amplifier - not amp modelling - plugins will allow that. The basic CMT LADSPA plugin collection[1] should provide that. Ardour has a phase inversion switch and some commandline utilities, including Ecasound[2] and Sox[3], allow that.
