Megaregions [1] provide some of this functionality but as James said, they are some way from perfect. I suspect there
are a number of bugs and some architectural issues that could be resolved (e.g. issues with terrain and messy
workarounds for oar loading/saving) but ultimately they are limited by having to work with a viewer that is only dimly
aware that regions can be larger than 256m x 256m (e.g. teleporting into a megaregion can involved an automatically
server-side invoked double teleport).
Having said that, some people use megaregions quite happily so it may depend on
the use.
The advantage of megaregions is that they should work with all viewers. To do it 'properly', I believe one has to have
specific viewer support (e.g. as Toni was talking about with the old Naali viewer). I imagine that multiples of 256m x
256m are easier than completely variable regions. Some OpenSimulator assumptions/bugs may also need to be resolved
though that might not be too bad since they've already been resolved for megaregions.
Some viewers already support variable regions (for Aurorasim for instance) so
it may not be too hard.
In other words, I believe we are likely to see the change in OpenSim but it requires a bit of work/co-ordination so it
probably won't happen tomorrow.

Enter Megaregions. Not perfect, but they work. I run one that is 1.25km square

At the risk of opening a real can of worms, what is the potential in the
future of changing the 256m x 256m limit on
sim size, and even moving to a single, near limitless sim.
It is the one feature of OpenSim that stops us using it/proposing it for
some of the really big projects we're
involved with, where even modelling just a 2km x 2km area becomes
unthinkable in OpenSim (64 sims?), but is trivial
in environments like Unity. I know that grids have total sizes well over
this, but generally each sim is operating
on its own, with few buildings overlapping sim boundaries and people being
very conscious of boundary crossings, and
trying to automate an object from one sim to another if non-trivial. In
terms of our aspirations just getting to
1/2/3km sims would make a huge difference, even if we had to stick with
existing prim limits.
I think that RealXTend Tundra has removed the limitation, and Vastpark
(which also has some OpenSim heritage) has.
Are we ever likely to see a change in OpenSim (and if it's "just" a case of
money, then how much effort?)
