...this is something we'd all like to add in the near future, but it's 
not there atm...or maybe I'm not reading your request right:  you could 
always mirror the displays and show one window on all outputs...or, you 
may be able to create a spanning window, as long as both displays had 
the same pixel format/bit depth/etc...

...Gem4Mac was one of the initial inspirations for me when I started 
porting gem to OSX, but it wasn't terribly helpful because it is really 
mired in OS9 era api's (and many things about it were never finished, 
plus it's been abandoned, support-wise)...so with the move to OSX 
windowing/opengl api's, the code just isn't applicable :-(  Don't loose 
all hope, because it is possible, just not until someone takes the time 
to hack it out...
