I’m disappointed to learn that “there are no plans for an official 64-bit version” of Google Gears.  Makes it hard to use Google Gears with a 64-bit Linux.  It’d also be nice if Google bothered to mention this in the system requirements, rather than burying the limitation in a discussion group.

Update: apparently there are ways to run Google Gears on 64-bit Linux.  I’ll have to check it out.
