ssh-ident allows you to have a single line in your .bashrc, then let it take care of loading ssh-agents when first needed, load all the necessary keys, and share ssh-agents across login consoles. If you have multiple identities for the same account, it is able to load different keys depending on the host you connect to or the path you are working from. At the same time, it keeps the ssh-agents separated and forwards only the keys which are needed for the specific host. It also allows you to specify ssh-add options, so you can automatically lock keys which are unused for a certain time, or have a confirmation request every time a specific key is used.
