Look at XSendEvent; it's about the closest thing the core protocol
provides.

I don't know of any wrapper program, though it shouldn't be hard to
write one.

If you use XSendEvent, note that the receiving client can tell that the
event is a fake event.  Some programs (eg xterm) can be set to ignore
such events; some of them may do this by default (offhand, I don't know
whether xterm is such a one).  Other programs ignore this bit and
process the event normally....

I think there is an extension (I forget the name, though rummaging in
my memory turns up "xtrap" as being possibly significant) which is
designed specifically to do journalling.  If this is right, and you can
find a copy, that should be capable of doing what you want.

You may find you have to switch to the MIT server (which will not
render most OW clients useless, though a few that use NeWS will of
course break).  The reason for this is that if you have to install an
extension, you'll need source to your server.
