Comment 9 for bug 62593

I see two possibilities here:

 (1) spawn e-a-n from e-d-s
 (2) add an /etc/xdg/autostart .desktop file for e-a-n to evolution

I'd prefer (2), it is the cleaner solution and also the one suggested by upstream in the upstream bug. (1) would have a better semantics, though (only started when necessary, can be --force-shutdown'ed if wanted, etc.). But having it always running should DTRT given that we don't want to miss meeting notifications :)
