Call me cynical if you will but that sound clip sounds suspiciously like a "real" UP chanter. In addition, I've heard some very very expensive instrument emulators in the music dept [...] Very close yes in some instances but never "exact". The sound clip for the vPipes sound "too" real. Hence my "cynicism". If I'm wrong then I take my hat off to the inventor.
vPipes-Uilleann is a unique electronic uilleann bagpipes emulator that uses revolutionary technology resulting in a real-life experience in terms of sound quality, fingering and ornamentations. It thus affords the possibility of practising accurately in a variety of situations that would prove impractical or impossible with a real set of pipes. The vPipes now includes the possibility of loading a whole array of MIDI sound-bank samples.
