The rules are being released under the Open Content license (nice to know that some folks are still using it, even if ahem, others are not. For more information, read the official press release or download the developer's kit.

I've never played Traveller, though as a longtime gamer I've heard plenty about it (and the hypercomplexity of some of its more detailed rules subsystems). Where I going to GenCon, I'd likely pick up a copy, but instead I'll content myself with meandering through the SRD.
