Can Skype Be Used for Testimony in Court?

The Indian Supreme Court is to deal with a challenge to evidence of the complainant in a rape case that was taken by Skype. The complainant is Irish and is now in Ireland, and does not want to return to India for the trial.

The accused submits that the quality of the recording is not good enough to admit the evidence.

Does anything about the use of Skype in this case, or in general, make you uncomfortable?

Can there be a firm rule about the admissibility of private (or quasi-public) systems of video evidence, or should it depend on the circumstances of each case?
