I use Yubi-Nano for email signing as well as authentication/security with gpg-agent for remote SSH. I haven't figured out the problems I'm having with multiple sessions/sockets, but aside from the need to recycle my agent from time to time, this is extremely convenient and exceptionally secure. I wrote a summary of this setup [1] a while back, that might be helpful, though yubikey has a good writeup [2] already.
