Hello I didn't see a thread devoted to this topic, and info on it is scarce anywhere, so I thought I would start one. I'm really looking forward to the new iChat service plugins. I prefer iChat over other IM apps, but I've always missed the lack of MSN and other service protocols. Lion's iChat adds the option for 3rd party plugins, and I wish I had any development knowledge to make my own, but I don't. So this thread should be a repository for service plugin links and info. First, is there any knowledge of anyone developing plugins? I imagine developers contributing to Adium or other all-in-one IM apps would be interested in it, since they already have knowledge of the various protocols. Has Apple released an official API for writing iChat plugins? Second, from digging around the Gold Master release it looks like the new Yahoo IM integration is done through a service plugin itself. I haven't tried yet, but I bet if you were to delete the plugin, the Yahoo options in iChat would just disappear.
