Condensed from MacNN, I don't have jaguar to verify or debunk the story:
MacNN notes that users with mac.com accounts using iChat cannot see anyone on a 3rd party client (Fire, trillian)
If you are on a AIM clone-client, you are not able to see @mac.com users.
Be clear - this is not a iChat application problem - this is a AOL IM service/.mac IM service issue. It appears that AOL has used the occasion of adding the .mac folks to AOL's AOL IM service to break the AOL IM protocol that all the opensource folks have worked on so hard.
There is another glitch with iChat. After being logged on for a set amount of time (not sure not long yet), iChat will stop showing the most up to date Buddy List, and you won't see messages that are sent to you. It could very well be a glitch with the way AOL IM servers react to ichat clients. Nevertheless, its a frustrating problem, and I was logged in using a standard AOL IM username, not a .mac account."
