Desktop-style window management

Hi folks,

I'm evaluating which GUI to port to a non-unixstyle multitasking OS with 
limited posix lib support. Although the CPU performance is more like 
"embedded", the use is a highresolution desktop rather than a small display.
Framebuffer implementation seems feasible, but the PDA-style 
windowmanagement of picoGUI is not suitable. Apart from windowmanagement, 
the picoGUI architecture seems to fit quite good.

In the FAQ I read:

[...] in theory PicoGUIshould work great on the desktop once more apps and 
drivers are written. Even though PicoGUIis usually used without overlapping 
windows, it does support them, and the PicoGUIserver is very scalable.
There is already work in progress on a Linux-based OSthat uses 
PicoGUIrootless on X as its native GUI, so PicoGUIapps can run side-by-side 
with X apps in overlapping windows. [...]

Does this mean overlapping PicoGUI windows are only supported via X, not on 
bare framebuffer without X?

Is there work in progress for PicoGUI desktop-style windowmanagement, esp. 
overlapping windows for multitasking applications?

Sorry if this forum is not the right place for my sort of question. Maybe 
you can give me a quick hint, thanks a lot.

Regards,
Peter
