64-bit Gem on Mac OS X could drop Quicktime/Carbon in favor of gstreamer and/or gmerlin which I believe is already implemented on GNU/Linux.  

That would throw away the advantages of QT on OSX, and I would probably no longer use GEM if that happened.
 
Then its just window management, which doesn't seem so huge, but I haven't done it before.

It would require interfacing the C++ code with Objective-C.  It is possible, but fairly masochistic.
 
Am I right in assuming that Gem could really benefit by 64-bit because it would allow it to use more than 4 gigs of RAM?
 
I cannot recall anyone ever saying they hit this limit.  Even the massive projects I did using many HD clips and capture never got close to this.
