I believe there is also a "-f cfg_file" option, to specify a config file
saved from the XConfig window. The other options specified on the command
line
then override the corresponding setting in the config file. This should
allow
control of specific items on a per-X-server basis (remote window manager
with
multiple window mode, font differences, unique display visual color depth,
etc.),
though I certainly haven't tested configuration of every option myself.
This would seem to allow working around several of the limitations listed
below, if they are an issue.

Hi All,
Multiple X Display Support
Support for multiple X displays has been added by allowing users to run
multiple, simultaneous copies of the X server (limited only by available
memory and resources) as long as each copy has a unique display number. This
feature is particularly useful for users who would like to establish
multiple XDM (X Display Manager) sessions with different hosts.
The following command-line parameters are supported by the Exceed X Server
(exceed.exe):
-d <display#>
-m passive|query|indirect|broadcast
-h <hostname>
-w multiple|single
where <display#> represents the desired display number from 0 to 9999
inclusive and <hostname> represents the connect host for the XDMCP-query or
XDMCP-indirect startup modes.
For example, to start the Exceed X server in single window mode on display 1
with a startup mode of XDMCP-query to host xdmhost specify:
home\EXCEED -d 1 -m query -h xdmhost -w single
For a particular command-line parameter, if you would like the setting to
default to its current Xconfig value in the exceed.cfg configuration file,
omit its specification on the command-line.
The easiest way to startup multiple simultaneous copies of the Exceed X
Server is to use Xsession. In Xsession, you should uncheck the Run X Server
option, add a New Program of type Windows App to the session for every copy
of the X server in the session. For each X server in the session, make sure
either the command line is fully specified or the exceed.cfg value is
suitable, and make sure a unique display number is used. Enter the session
description text in the Description field, save the session, and install a
program shortcut to enable double-click startup of the session.
In a future release, Xsession will let you specify the startup of multiple
copies of the X server with different display numbers without the use of the
above command-line parameters. At this time their direct use will be
discouraged.
The current implementation of multiple X display support has several
restrictions or caveats. For example:
1 Since all X displays currently share the same configuration file, do
not make changes to your configuration while the X server is running.
2 Since only one X display can own the desktop/root window and the
configuration file is shared, do not enable the following Multiple Window
Mode Xconfig settings if you are using the multiple X display feature: Root
Mouse Actions to X, Root Drawing, and multiple screens. You can still use
the Root Mouse Actions to X toolbar button, but make sure the setting is
only selected for one X display at a time.
3 Colormaps are not shared between X displays which may result in
color flashing in 256 color video mode when you change the focus between
windows that are on different X displays.
4 Multiple copies of the X server cannot share a single log file. To
solve this problem, the name of the log file in your configuration file is
used to construct the log file name for each copy of the X server in the
following manner: if the log file name in your configuration file is
exceed.log, then each copy of the X server will use a log file whose name is
exceed<display#>.log
where <display#> is the display number of the X server.
To disable support for multiple X displays, set a value named
DisableMultipleXDisplays to 1 (DWORD) for the registry key
HKEY_LOCAL_MACHINE\Software\Hummingbird\Exceed\XServe r in the registry
database.
Mit freundlichen Grüßen / Best Regards

I'd like to simultaneously open sessions from my one PC on two different
UNIX machines. How do I do so?
Thanks
Philip
