Ah, the hairs are splitting more finely than I thought.
I think your screen saver is a derivative, which would
fall under 4.b of the license, not 4.a

http://creativecommons.org/licenses/by/2.0/legalcode

And 4.b doesn't have any "technological protection measures" TPM clause.

I think the TPM clause should be removed from the attribution license,
but that's a different debate.

I'm not a lawyer.  This is not legal advice.
