My point is that there are only two options available in, but 
there is a third:

1) Seamless mode where each XWindow gets a MacOS Window.

2) Full-screen mode where X11 takes over the entire display (and does 
not show any other Mac apps, Dock, menubar, spaces doesn't work, etc)

3) Windowed mode where X11 opens a single window, which maps to an 
XDisplay.  Inside that display, you can run a window manager, etc, in a 
full X11 environment.

Apps like Microsoft RDP, Mac Remote Desktop, VNC, etc, all have options 
for full-screen mode or (single) window mode. only has 
full-screen or seamless, but lacks single-window mode.  I believe Exceed 
(Windows app) has multi-window, single-window, and full-screen modes.

I'll try using an alternate wm and spaces as you mentioned.
