Pretty much everyone these days has used Yahoo Chat, MSN chat, etc etc.
From a corporate perspective some questions are being asked of me regarding the zimbra "Instant Messaging" feature that I am no where near qualified to ask.
Does the IM feature support video?
Does the IM feature support voice?
Does the IM feature support file transfer?
If no, are these features on the product road map? The features requested are real features really required by true distribuited organizations.
