Couple points worth noting from that demo of Sansar that Linden Lab CEO Ebbe Altberg gave last week:
Conducted at a Wall Street Journal conference, Linden Lab also created Sansar avatars to look like WSJ reporters (see above), with the subsequent story highlighting Sansar's use for enterprise: "Get ready for virtual reality meetings. And yes, you can stay in your pajamas." Pretty noteworthy that Linden Lab seems intent on pushing Sansar for business use at least as much as for consumers.
Another point from Variety, which reported from the WSJ demo:
Sansar’s early beta testers have not just been Second Life creators, but also some that don’t have any experience with Second Life at all, and are able to start with a clean slate. Linden Lab opened up Sansar to a small group of creators in August. More than 10,000 creators had signed up for access.
Depending on how you look at it, 10,000 people so interested in Sansar that they want early access as developers is pretty impressive... or not too impressive at all.
