I thought I'd try telepathy out this morning, but discovered that the install seems to be broken.
When I try and add an account, I get a popup:
"Something went terribly wrong and the IM system could not be initialized. It is likely your system is missing Telepathy Mission Control package. Please install it and restart this module."
I did check in MCC to see what was loaded of Telepathy and it seems the control module is installed. I thought I'd uninstall it and try again, but when I unselected it, the system wanted to basically uninstall kde so I gave up.
