This sounds horribly difficult to implement in the way you describe...  you
don't however say whether you are running the applications on Windows or X
or what.  If you ran them on X, you could simply have a big huge Xvnc
desktop and layout your applications on that.  Under Windows or on the Mac,
you would simply connect the biggest monitor you could find and connect
that way - some graphics cards allow very large desktops up to nearly 2000
pixels across (but few monitors support that).  Of course you could run the
box headless if you didn't have a monitor that big, but you'd still want
one of those monitors to display it at the client end.

Remember this was what windowing managers such as fvwm and Windows were
designed to do in the first place - make the most of a small desktop in a
user-controlled way.  Obviously if you have a lot of stuff which you MUST
put side-by-side, you need a huge desktop, plain and simple.
