this may sound very silly, but if the problem is that
- we don't want one panel setup / deskwidget per _NET_WM_DESKTOP (e.g. to save 
memory or whatever)
- panels and desktops appear different depending on _NET_WM_DESKTOP

where's the problem with having FX that rely on displaying multiple desktops 
(aka the grid (all), the cube (at least two))

- set _NET_WM_DESKTOP
- trigger an update for the panel/desktop type XWidget
- copy the composite output into a buffer
- increase _NET_WM_DESKTOP
- ... loop on

this of course a little bit breaks the idea of the composite extension, as 
these windows do no more represent the current state of the window but some 
kind of pre-composite static buffer, but

- it applies to few windows
- those will likely not change the apperance (alot) as
- the effect is usually only displayed for a  short while
- one desktop can remain "live"
- we just ruled out a parallel solution...

(in principle, this could be applied ot all sticky wins, but that's probably 
stupid)

just for the records:
i like neither hiding (why should one?) the panel nor keeping it global (as 
long as it's not fully interactive as well)
