Creature permission 'renting' (for cross-server animals). How would it work?

[Benie 49]

This thread is based off of my (apparent) one-sided suggestion about dealing with a lack of permissions when it comes to bringing your favorite animal cross-server.
https://forum.wurmonline.com/index.php?/topic/163327-keep-permissions-on-branded-animal-cross-server/

Now I realize that throwing a tent down outside of the perimeter of a deed and hitching the horse, is a good workaround to not having perms cross-server. But there's an idea someone gave me, that I don't know where to post it (or even if people would be willing to incorporate this system).
The idea, was of trusted individuals on every server, willing to 'rent' a spot for one's horse (where they would brand it and then turn perms over to you). And as long as this person's deed stays, the perms will.
But how much would such a service cost, and would it be based of a RL day, or a RL month? Like for example, I give you 25c and you brand my horse, and let me use it on your server for a month.
But this becomes a problem that the person would have to be active, and write down the names of all the people they're helping with this, and how long until the month is over.

I hope to have a civilized conversation about this (or something related to this). And to the mods, please move this thread to wherever you feel is appropriate for this kind of discussion.

I imagine the easiest way is to have a stable of unbranded horses with keys sold on a merchant. Renter buys the key for full price then when done brings the horse back and cods the key back to the stable owner for a price less than the original purchase price.  So if horses sell for 80c and the rental rate is 20c the cod back is 60c.  The advantage is that the system can work 24/7 and the way to cheat it is on the stable owner not buying the key back.  Since they would quickly lose a fairly profitable business doing this they have an incentive to return the deposit.

I like it, however, you have confused me on "if the horses sell". This is for importing one's horses cross-server, not buying new ones.
