There is a new proposal on the Linden table. It comes from Toysoldier Thor and can be found in the JIRA as: SVC-8082 – Proposed Global Service for SL: VIRTUAL LANDMARKS & VLM Mapping Services.
Consider what happens when you have a home or shop in-world and your landlord decides to return the land to Linden Lab or for some other reason you have to move. The land is either going to disappear and all your stuff will be returned or your shop or home will be gone. You find a new house, apartment, and/or shop. There is little that can be done to stop that process.
But, consider. What about all the Landmarks that point to your shop or whatever that no longer exists? What do you do with the dozens to thousands of links in the Market Place to your non-existent shop? Did you know there is no easy way to just change the landmark you have included with a product you have for sale? You have to reload the entire product package.
This is such a problem that many merchants no longer include a landmark in their Market Place packages. If their landlord gives up their region, boots them, raises the rent, or whatever, they have to move and change all their landmarks.
As Toysoldier said, “If a mall or club wants to renovate [or] move an LM temporarily they can’t, not without tons of LMs pointing to the old location.”
The fix for that problem is Virtual Landmarks. So, how does that work? The answer is: very much like the Domain Naming System (DNS) that we use for web sites.
When you type in the URL blog.Nalates.net your browser via your computer sends a request to the DNS service asking where Nalates.net can be found. The service ends back an IP Address (Internet Protocol). Your browser can then send a request to that address.
DNS allows me to use the domain name with hosting on Go Daddy or any service I personally prefer. Freedom is good. All I have to do is go to my domain registrar and change the IP Address for Nalates.net. All requests are sent to the new IP address at the new hosting company.
The proposal is to do something like the DNS for landmarks. You could make a virtual landmark (VLM) that to the user would look just like a regular landmark. From their viewpoint it would work the same as a landmark we have now. But, it would sort of be a landmark that points to a second landmark. You, and only you, would be able to change the second landmark whenever you want. The result is when using an old VLM you would arrive at my new shop, no matter how many times I move.
