A first step of Skype integration could be to give people a field in their profiles to put in their sip:user@domain address and give it the function if you click on it a Skype chat is opening. This Skype address should be shown also on the profile preview. Would be great first step towards O365 integration.

It would be great, if events had also a field for adding a online-conference link (Skype, or other too).
