Sync iPhoto library like syncing an iTunes library

[guitarist]

iPhoto does not currently offer that kind of synchronization, as far as I know. But newer versions of iLife/iPhoto, you can set up iPhoto on each of the macs on your network to share libraries, and view each other's libraries, configurable in preferences. In that regard, it's very similar to iTunes. It uses Bonjour, and works and acts similarly to iTunes sharing. But syncing? Maybe that's come in some future update of iLife.
