Basically the chooser works this way:

If the gdm daemon gets an indirect query it runs a chooser for the user and
then next time the user does an indirect query it forwards the query to the
appropriate host.  To set it up locally what you would do is enable
xdmcp on the local machine, enable indirect queries and then run
X with "-indirect localhost".  For example to currently do a chooser on
the local machine as the main display then add a new server definition
such as

[server-Chooser]
name=Chooser
command=/usr/X11R6/bin/X -terminate -indirect localhost
flexible=false
handled=false

Now in your [servers] section
write

[servers]
0=Chooser

In the GNOME 2.4 version (gdm v2.4.2.97 is the current devel release) there
is an actual chooser server type so that you don't have to run xdmcp on the
local machine.

Also good to try is to run 'gdmXnestchooser', that runs Xnest for you with
'-indirect localhost' so that you get a chooser and an X session in a window.
