Click-to-dial in Mac OS X Address Book app
This should hopefully be super-easy to implement. The Address Book app in Mac OS X allows for plug-ins to enable capabilities for things like click-to-dial. I would love to be able to preset a username, password and telephone registration somewhere on my mac and call directly from my contacts. Skype already provides this kind of functionality.
