This is some awesome work!
From the looks of it, your window server architecture is similar to wayland's, so would it be possible to port the GUI library to Linux/Wayland?
Then someone could write a wayland compositor using wlroots that mimics the W95 aesthetics and there you have it: the ultimate 90's UI on a system that's actually usable for day to day tasks.
Sure, the GUI library could definitely be ported to anywhere POSIX-y. The IPC messaging is already based on AF_LOCAL sockets so that should "just work"
The bitmap sharing between WindowServer and clients is using a custom Serenity API ("create_shared_buffer") which is specifically tailored for this system. It can probably be replaced with some equivalent X11/Wayland mechanism in a few hours, if someone felt inclined to do that. :)
