We are also about to be a Jabber environment and are increadibly interested in this topic as well. Our interest is in having Jabber presence with the capabilities of IM and calling in Alfresco. Because our Jabber installation is tied into our phone system, each user would essentially primarily operate in Alfresco with instant access to our employees via live chat, video, and/or voice anywhere you see a contact link. I feel this would bring huge competition against Sharepoint and also drastically improve Alfresco's collaborative surface even more than it already is. You would essentially have instant video/voice communication directly from an Alfresco document, store, or team page.
If anyone has any information on this, it would be incredibly useful to hear. Thanks!
