Not to me, because it's analog. Every other protection leaves the final "played" content alone. Not Cinavia. Once all decryption is done, it's there, in the unencrypted analog content. No other protection removal requires manipulation of the unencrypted analog content itself in order to defeat it. That means that you lose the original audio codecs and it will have to be recompressed into a consumer accessible format, if it's possible to remove it. That means no 1:1 ISO option for Cinavia removal. No other protection is like that.
The only "real" solution to me is a Cinavia free player, either HTPC, an older Blu-Ray player that cannot physically support cinavia (which I suspect might start to sell for inflated prices on ebay), or a newer player that might be able to be modded to "turn off" Cinavia (I'd keep an eye on JVB Digital for that, if it's even possible that is; I strongly suspect it isn't). There's also the possibility that someone might make some kind of hardware player that plays unencrypted content only (no AACS license, so no cinavia). However, I'm not sure if it would be able to handle all of the commercial audio and video codecs without needing any kind of license.
