Just found an excellent plugin to add Skype support to Pidgim IM (also works for Adium as they both use libpurple).

This in conjunction with the Facebook plugin, make pidgin/adium a kick ass IM solution:

Edit: The only downer of this approach is that Skype has to be running locally in order for the plugin to function....
