DBus-using Library Design
As a rule of thumb, when writing a library which uses DBus please always make asynchronous DBus method calls. You never know when someone will write a system using your library which, via a series of plugins, ends up calling itself. A single main loop and blocking DBus calls are not a great combination, and leads to lots of frustration.
Yes, libnotify, I'm looking at you.
