I can give a little additional insight... SGI visualization systems 
(Prism/Onyx)
can handle this no problem, they're designed for fast multi-head graphics,
any recent nVidia dual-head cards will work too, under either WindowsXP
or Linux with Xinerama (never tried a quad configuration), I've never tried
a Radeon but I suspect it would work for dual-head VTK on Windows.
