Is There A Second Job For You Via Your Own Avatar?

Sitting one row ahead of an animated conversation on a recent cross-country flight, your tech-savvy author was utterly confused as he eavesdropped on this discussion about somebody's "second life." The befuddlement ensued because a second life is often how people describe the time after a fateful event such as a divorce or getting fired. But the conversation I had cued into didn't include ex's, lawyers or hated bosses. Instead this story included names like Apache, Squid and Havok, plus talk about textured primitives for somebody's avatar.
