Thanks to Anders, Tim, and Eric for pushing on this particular item.
It's led to a pretty exciting discovery called the Camenisch-Lysyanskaya
(CL) signature scheme, which stems from a paper that's almost 13 years
old now:

An Efficient System for Non-transferable Anonymous Credentials with
Optional Anonymity Revocation

http://groups.csail.mit.edu/cis/pubs/lysyanskaya/cl01a.pdf

This could solve a number of the privacy concerns that we have around
credentials. IBM based their BlueMix credentialing solution off of it.

We need to dig a bit deeper to see if it's patent encumbered and speak
with the paper's authors to see if it's practical to apply it to our
work on credentials.
