In addition to Paul's response there is a much heavier solution: Install Fedora Directory Server (FDS), feed it the proper schemas that work with Thunderbird, Evolution and LookOut, add the contact details and configure the LDAP server in those clients. The only HOWTO I could find on this subject is Evo1 related and iirc it's not very helpful for Evo2. I recall reading in the FDS irc channel that someone would submit a schema for Evo2. Don't know if that's available yet. My guess is that this solution takes much more figuring out than Paul's contagged app. The advantage is that once your contacts are in FDS you can probably use them with CRM software like SugarCRM, vTiger, CentraView or CentricCRM too. Alternatively you could have a look at Scalix. It is not OSS but iirc it does use an LDAP backend. Open-Xchange is another one that has groupware support for multiple clients and LDAP.
