Yes, and that's because of the case where the user runs multiple X sessions
from the same account, on the same host - IIRC we decided it should have different
dcop servers in that case.
Maybe the fix, to make dcop available without X too, is as simple as
"if no DISPLAY is set, then use ~/.DCOPserver_NODISPLAY instead of
~/.DCOPserver_$DISPLAY" ?
