Wayland the "successor" LCA: The X-men speak

Maybe. :) But it's not that obvious.

It does not require kernel patches. It only builds a fusion kernel module for fast IPC. And it's much farther from X-server than Wayland.
> It has no real support for running OpenGL applications
DirectFBGL? You can see some 3D-looking samples in http://ilixi.org/ video.

Weston can also do simple compositions. It's up to the compositor, I guess.

I don't remember it ever trying to support OpenGL, but I guess that blitting from a texture to framebuffer is not that complex to add if you have a working EGL.
In short, DirectFB is more like a classic framebuffer with several hardware accelerated operations. It's not nearly enough for modern graphics.
