A Funeral For Teen Second Life: A Presentation From Beyond the Grave on the Future of Mixed-Age Education in Second Life.
Eulogizing Teen Second Life over the open casket of his Teen Grid Avatar, GlobalKids Bixby will share his deep grief over the loss of Teen Second Life. Meanwhile, a surprise guest will celebrate the end of Linden Lab grid for teens and herald the new age of mixed-grid education in Second Life.

Birth of 130,000 Teen Opensim Quad-Sim Standalones
Scott Provost, Director at Free Open University, Washington DC, writes: "We plan on proposing 130,000 Standalone mega regions (quad-sim with 180,000 prims) with extended Hypergrid services... If 130,000 schools in the USA have their own server with courses loaded in them. Remote instructors and at home student could log in or Hypergrid to them."

This idea looks like minimum 260,000 concurrent users on a good day, in comparison to Teen SL with maximum 200 concurrent users on a good day (six years long)... Or minimum 5 times the mean number of concurrent SL users... 130,000 invisible standalone residents with quad-sims = 520,000 sims...
Concurrent User Metric Lag
Teen SL had 197 regions, and in the course of 6 years, the maximum number of concurrent users "even on a good day" was 200... What do you expect if the education outreach metrics lag, next to SL lag?
Concurrency
OpenSim doesn't have the same lag problems as Second Life, since each grid is its own separate entity, hosted on separate servers on different networks.
If 100 schools had their own grids, it's much like 100 schools having 100 different websites -- the performance of one website isn't going to affect the performance of any others.
Hypergrid does allow teleportation between different grids. But even though hypergrid teleports feel a lot like Second Life's internal teleports, you're actually landing on a different grid, and your grid of origin hands you over to your destination grid (while still continuing to supply your avatar, clothing, and accessories). In this case, your avatar will impact the performance of two grids, instead of just one.
As a result, hypergrid teleports aren't that much of a burden. In any case, most school-based grids will probably have hypergrid teleports turned off - at least, while regular classes are in session, to keep strangers from dropping in.
