I was bored with feeding my SSH-Agent with plenty passphrases. Gnome-Keyring and friends just displeases me because of all their dependencies.
I would love to have a slimy, gui-less keyring which fits well into my environment and toolchain. But it seems to me that I / We've still got a long way to go. My Easter-Hack-Project SSH-Keyring (github-mirror) tries to solve a nibble in a hackish way. Code reviews and suggestions are welcome.
