I think the distinction will be a matter of System Defaults. Xor is the underlying System. Will name resolution be a default part of the network, that is managed by the network as a top-level domain, or will it be a subcategory of action on the network?
If it is the former, it’s a default system and substituting an alternate service would be a workaround.
i.e., safe://“petname” = safe://(xor address)"
If the latter, then alternative lookup services would have an even playing field to operate in.
where safe://lookup by itself would return an error message requesting a service address.
I know this seems odd, but would democratize and give an individual control over which services they wish to filter with. Would also allow individual controls (e.g. parental filtering) to be controlled by account or device.
Xor addresses can be gleaned from any service’s listings, so would be completely open sourced. Let the competition for favored filtering or preferences be in complete play.
This would allow for different “webs” to be shifted between, while the underlying infrastructure would be open for use to everyone.
Basically, then, safe://(xor address) would take you to the sight at any point, but for look up, you could use the Service of your choice. Services could come as defaults to different browser versions, or be modified by the user.
So default lookup on the official Safe Foundation browser (installed with base software) (e.g., safe://lookup/SafeLookup) could have limited default directory of addresses that direct the user as to how to use the system according to their preferences, filters, parental controls, and have an index of sites that give the info on the network and its use, including suggestions and instruction as to how the user can locate the lookup services they want, and how to set these as default. This index could have a variety of sites as seems prudent to the Safe Foundation and be very uncontroversial, apolitical, proper cautions, etc.
Beyond that, the user-selected browser and default service is completely free for the public to choose, according to their filtering inclinations, which everyone will have and competition will be rife.
