a second important audience, Linden Lab is targeting, too, is the corporate audience, the educational institutions, etc. Despite Linden Lab's propaganda, this is a very small market today (the majority of earnings comes from consumers) but it is growing. This audience needs more "control & security". If Linden Lab wants to succeed in these markets, they have to provide that - not only on seperate estates, because the vast society of Second Life CAN be an interesting aspect for some of these projects, too :) Not all of them work best in a walled garden.
