That's a different field entirely. Just because some American hospitals have trouble organising medical ethics reviews, does not mean that European or even American CompSci researchers will run into the same problems. Indeed, Daniel is (I think) positive perhaps based on good interactions with the ethics committee here (my wife is certainly happy with the ethics reviews she's had).

Even in that SSC discussion linked, many SSC commenters agree that their own ethics system was far easier, even in medicine.
