[sldev] Sim Size Limits?

[Zha Ewry]

The client makes a bunch of 256x256 assumptions. It *knows* where the
edge of the sim is,w hen to hand off, and if there is a sim adjacent,
based on it's geometry of the grid, and the handles of the sims it is
talking to. Breaking that is both a protocol issue and a code issue. I
expect, in time, it will be tackle,d but I agree that it's less of an
urgent issue than many, many other issued, including, as Soft
mentioned, having crossing be less disruptive.
