<div class="moz-cite-prefix">I don't think security has been holding
this up. Security is an issue in OSGrid, only, but there are ways
of mitigating it. The major hold up is that it's not trivial to do
the handover of these objects, and no one with enough technical
skills to do it has had enough motivation to do it in core. I tend
do to this kind of stuff (moving things around servers), but, as
you can see below, I don't have any motivation to do it, because I
believe that border crossings SL-style are an inferior solution to
the problem of moving vehicles within large areas. Instead of
following that solution, I invested my time in figuring out how to
do co-simulation in order to avoid borders in the first place.<br>
<br>
This is my perspective on the issue. I can't speak for others.<br>

</tt><tt>For me, they got a lot less important now that
OpenSim supports variable-sized regions. There are
also alternatives (co-simulation) to moving vehicles
along very large areas that are able to avoid crossing
borders altogether, therefore avoiding the "bumps" on
borders and the extra load that moving vehicles and
crossing borders entail. These 2 things (varregions
and co-simulation) don't exist in SL, but they're
superior in some respects, because they avoid crossing
borders altogether; it's much smoother, keeps the load
down, and avoids running into security issues.</tt><tt><br>
