In that post badspot explains that it was capped at 128000 so it fits in 17 bits, it was then raised to 256000, so I guess it now has 18 bits, he could easily add another one
In his post he says that the only effect is that the ghosting time would be a minute longer, oh my god, who cares
The real solution is to totally rewrite the inadequate method of data transfer that Torque uses.
262144 is the limit of
server objects ("ghosts") and datablocks combined, not just bricks. The brick limit has consistently been lower than the object limit because there needs to be extra room for non-brick objects.
262144 max ghosts - (4096 max datablocks + 256000 max bricks) = 2048 non-brick, non-datablock "ghosts"
