Sonoko is a big x11-terminal able to manage up to 3 physical LCDs and 5 virtual screens (with/out Xinerama), all made with embedded Linux boards.

.. an embedded Linux workstation running off an image unpacked from storage for each new user, is both easier to maintain and more cost-effective. You can do this relatively simply using PXE boot on any machine you can secure the BIOS/EFI/OF for. Funnily enough, in these use cases, a LOT of RAM (say, 32 GByte) would make it possible to run a full desktop system off a RAMdisk without any customization work or any kind of local storage, with reimaging taking only seconds (assuming GbE Ethernet networking, or faster) -- the entire filesystem is transferred as a single XZ-compressed image, or as a few trees depending on the user logging in. Unfortunately, most embedded machines are limited to 4 GiB or less, which is not really enough for a full-fledged GUI Linux distribution.
Many Xterminals made in the 90s ran only the X server on the terminal, and the applications themselves on bigger iron (i.e, as "thin clients"). The difference is that the machine runs everything locally, from a ramdisk. Nothing new. It's just that having big-mem embedded machines would make that so much better. The CPUs are easily powerful enough already.
