I've been giving this a lot of thought and figure I could put in a suggestion that could be beneficial
for all estate/region owners, "grid runners" and such.
I've been running my own estate with 9 regions and would like to enable
an ability to visit other estates/regions without the necessity of being tied to a grid network.
So, instead of being limited to a grid map and "available" regions ..
just set up a system where all estates/regions are listed on a visible central database.
This eliminates the need for a grid map and the fuss over available space.
The only thing necessary then is to maintain the list of hyperlinks.

Dolph,
There are a few sites that maintain HG destinations, like http://thehypergates.com and http://hypergridbusiness.com however the locations and various versions of the simulators can vary quite a bit. HG destinations are still subject to 4096 region limitation just like regions within the grid.
