Well, some very smart people at Microsoft, IBM and other places seem to think it's a worthwhile pursuit. See Hoppe's paper on "Robust mesh watermarking." I don't even begin to understand the high level mathematics involved in "Multiresolution Wavelet Decomposition," "Mesh Spectral Analysis," etc. but apparently these guys do and apparently they think it's doable. Now as to how robust "robust" can be, once you start hacking an arm and a leg off here and making things unrecognizable, all bets are off. ANy watermarking scheme can be defeated if you alter the content sufficiently. I think the point is that if you have the skill and the time to make Vicky Un-Vicky, beyond DAZ's ability to prove she's theirs, why not make your own to begin with? Actually, of course, they only have to keep you in court beyond your ability to pay a good lawyer I imagine. No lock is going to stop every thief, but that's not what locks are for.
