I'm pretty sure it's a miniaturised version of a Rohloff, a small plantetry gear set up. Very neat, not overly light at the moment, but certainly a good idea.
Comparing similar suspension designs and saying they're the same really isn't a good idea, there are only so many effective and efficient suspension designs so designers are limited by this. It does look like the Orange, with looks like a Commencal, but i'm sure they all ride differently and have their own traits. I mean the Giant Maestro linkage is similar to the DW linkage on Ironhorse bikes, which is similar to the VPP set up used by Santa Cruz and Intense; having ridden a few Iron Horse Sundays and owned a few VPP bikes and a Giant Glory i can safely say the subtle differences between them in pivot placement make a world of differences, even though they all look very similar and work on the same basic premise.
