When using a X back-end, the environment variable DISPLAY specifies
the host, the display and the (default) screen.
The argument of -NSHost should accept a syntax depending on the
current back-end. With intelligent defaults, it may accept similar
expressions whatever the back-end. But in anycase, it appears that the
interpretation of its argument is back-end specific.
So, for the X back-ends, we could have:
-NSHost [host]:display[.screen] | host[:display[.screen]]
When host is not specified, a X server on the localhost is used. But
be careful : X connects thru the unix-sockets when no host is
specified, but thru the network lo0 when localhost is specified.
When no display is specified, :0 should be used by default.

That's to avoid that kind of problems that I propose to use the X
clipboard instead of a GNUstep specific pasteboard server. At least
with the X clipboard we have a similar service to implement our
We sill have to resolve the cases of notification centre and workspace
I'm afraid a good solution will involve configuration files (or
default entries). Hey, by the way, what about the defaults database?
[here-host]$ dwrite MyApp MyDefault Value
[here-host]$ ssh remote-host Apps/MyApp.app/MyApp -NSHost here-host
