That's why we told Philip, after 1.2 was published, that the Lab should work toward sims being larger (512 or 1024 squared) and being the smallest billable chunk of land. We learned two things: how hosed the database coding, or lack thereof, was and that Philip didn't, and never would, understand the virtual land rental business. He cried the day that private estates surpassed the number of Linden-owned Mainland sims.
Linden Lab could now be functioning as a host, supporting just a few hundred users, with the rest of us paying tier to private estates and being supported by respective staff. A bit of feature and interface development would add value to the service but would preferably be outsourced to a professional shop.
