There are two things they can do with the watermark: revoke the device, and sue the person who bought it. You can't get an AT&T SIM card or a DTV smart card without a contract. The only difference between those and a DVD player is the form factor.
Given a budget of $10k, I'm pretty sure I could obtain either one of those anonymously.
How hard is it to forge the required identification or bribe a store clerk to not check identification?
If someone's house is broken into, are they going to be liable for piracy through their stolen media player? (Assuming there's a several hours before it can be disabled)
The value of an anonymously acquired media player would be a lot higher than either of those two things. There's no market because nobody is willing to pay $1k for an anonymous cell phone when they can just get a prepaid one. But if one absolutely needed an AT&T SIM card, with that budget I'm sure they could forge all the required identification.
Of course it's hard to speculate the difficulty of such forging in the future. But I would think that $10k would be enough to break some human link in the chain.

I don't know. Where's the thriving and accessible black market for AT&T SIM cards and DTV cards?
And, with regards to "are they going to be liable", I direct your attention to the track record of the RIAA.
