Unix: All you need to do is set "$BBDISP" to point at your dev box.

You can do that in the existing client, no reinstall of the client
necessary... just hardcode it into the ext script until you're ready to
go live with it. Of course, doing development work on a development box
is good practice, but as long as your test doesn't do anything
dangerous, you'll be OK. 

You can execute the script directly from the command line until it's doing 
what you want. Just set your environment variables, thus:

BBHOME=<path to directory holding runbb.sh>
export BBHOME
. $BBHOME/etc/bbdef.sh
BBDISP=<dev server hostname>
export BBDISP

The sequence matters, because you want everything to be the same except
BBDISP.

What happens is, when you run the script, the BB client runs once,
delivers the information where it's told, and unloads. Do remember that
your test will turn "purple" after 30 minutes, so you may want to clean
out your history information under bbvar every time you get finished
experimenting.

I have no recent knowledge of the Windows client, though I expect to get
some fairly soon... it shouldn't be difficult, though. Anyone?

Of course, depending on what the test is, it'd be simple enough to
emulate the test on a separate machine. 

As regards sockets, the only place that's a concern is on the server
side. If your test server instance is on a different machine/IP, that's
all you need. The clients will simply open outgoing ports as needed...
unless you're using an unusually large number of outgoing connections,
you shouldn't have any problem.
