I can not go invisible on MSN with telepathy-haze backend (actually butterfly did this correctly). Trying to do so will make you busy on Empathy. However, AFAIK, it should be possible to do this with haze since pidgin supports this since a long time. I also found this bug which might be slightly related. I think a similar situation is with AIM in that report. https://bugzilla.gnome.org/show_bug.cgi?id=550502
Well, connecting via goa is not haze. My bad.
