I'm sure this has crossed your mind, and I only mention this as you seem
to have a deadline that Apple might not be able to meet, but have you
considered running a linux based PC instead of your PowerMac? Or <gasp>
a windows PC? Your graphics adapters should work in an x86 box and my
multi-monitor experience on these platforms has been pretty positive.
On Win32 I have run IDL apps on a quad monitor setup very similar to
your 3 monitor setup (3 1600x1200 as display with 1 1280x1024 for
control) w/o issue using nVidia "dualview". On x86-32 linux I have only
worked with a dual monitor nVidia based system . Maybe someone with
experience running 3+ monitors on linux+IDL can post their thoughts.
