You must've also become so wrapped up you've missed who develops it.
Not to be funny, but while it sounds exciting, A6 Game Studio sounds good on paper; but actually using it is a very different matter.
Another point to make, there would be no way to integrate this without a heavily modified version of FPSC.
There isn't much revolutionary about this system, developing an MMORPG Server<->Client System isn't really the major issue.
Having the hardware, providing constant maintainance, creating it to handle "Nth" characters seemlessly, developing the engine around the network so it doesn't become dependant performance wise on either.
Most MMO Systems, require specialised solutions. Otherwise you end up with ROSE, Gunz or Priston Tales style Ping-Rates.
If features like this were warrented for FPSC, then they would be developed in-house.
