Hmmm. What do you exactly mean? I´m pretty sure that you can call skype-out or voip calls even if you are not logged in to those services. IIRC they should log in automatically when you start calling. At least I have options for different kind of calls in Contacts.

Also you can make different kind of IM profiles that you can select with 4 clicks from desktop view. But it´s true that it´s bit too many clicks.
