Hi Christian, how about Riecoin?
http://riecoin.org/Supposed to be launched Tuesday night, a new primecoin algorithm, CPU miners only...
they will publish their algo only at launch day. Hmm. Prime number search seems rather
difficult even on GPUs. it requires BIGNUM maths, which is hard to implement on GPUs.

That would be interesting. If implemented cudaminers would crash a true CPU only coin.
