Unfortunately it doesn't really help with case-insensitivity, as it is a non-blocking async interface, so the listeners get told way too late. Plus you have to have every directory open that you want to monitor, which would get silly.
I think inotify does not require you to have an fd open for each directory, that was the motivation behind its design: GNOME needed a way to monitor removable media without blocking its unmount.
The rest of your points about maintaining a userspace dcache seem to make sense, though maybe trading memory for syscalls in the meantime would be worth doing (until the kernel provides more support).
