gpg public key
I setup a gpg keychain today (finally). Here it is.
I also submitted the key to subkeys.pgp.net
During the course of setup, I started fiddling with gpg-agent, to get ssh-agent like functionality out of gpg. I must say..I haven't quite ironed out the details for working with ssh-keys with gpg-agent. I made the modifications to get it to work, but it seems the first time you run ssh-add, it requires the passphrase protecting the ssh-key, and any subsequent needs for the ssh key passphrase, require the gpg key passphrase. I probably have something tweaked wrong.
Go gpg goodness!
